In addition, Megretski further teaches, wherein the digital control signal comprises a level select signal, wherein control signal eB corresponds to the claimed level select signal because eB controls the power supplied to the PA and is expressly disclosed as “the signal modulating the power level of the PA” [Col. 11, lines 42-43], and “a signal representative of the voltage level to be applied to the PA” [Col. 10, lines 60-61] Regarding Claim 95, Megretski discloses the limitations of claim 95 as recited above in the rejection of claim 93.

In addition, Megretski further teaches, wherein the RF signal to be transmitted is an input signal or a modified version thereof, “the actuator 200 (DPD engine) receives the input signal u ” [Col. 12, lines 28-29], and “The actuator 200 predistorts the signal u to generate the predistorted signal v” [Col. 12, lines 33-34] Regarding Claim 101, Megretski discloses the limitations of claim 101 as recited above in the rejection of claim 93.

Patentability shall not be negated by the manner in which the invention was made 07-21-aia AIA Claim s 37, 56, 97, 99 are rejected under 35 U.S.C. § 103 as being unpatentable over Megretski et al. (US 10931238 B2, hereinafter “Megretski”), and further in view of Yu et al. (US 9628120 B2, hereinafter “Yu”) Regarding Claim 37, Megretski discloses the limitations of claim 37 as recited above in the rejection of claim 36. In addition, Megretski further teaches, the nonlinear combiner is configured to combine the first signal with the digitized analog signal to generate the pre-distorted signal, “The actuator 200 predistorts the signal u to generate the predistorted signal v based , in part , on e” [Col. 12, lines 33-34], and “an actuator (predistortion) block that depends on both the signal itself and the envelope” [Col. 8, lines 58-59], and “generating, by the digital predistorter, based at least in part on signals comprising the input signal u and the first signal, a digitally predistorted signal v” [Col. 9, lines 13-15] However, Megretski does not expressly teach, wherein at least one of the one or more preprocessing blocks is configured to translate the index signal to a digitized analog signal correlated with the analog response produced in the one or more components of the transmit chain. In the same field of endeavor, Yu teaches that RF feedback signal 115 is produced from the output response of power amplifier 108 and is fed back through signal analyzer integrated circuit 102, wherein at least one of the one or more preprocessing blocks is configured to translate the index signal to a digitized analog signal correlated with the analog response produced in the one or more components of the transmit chain, “The output signal 115 of power amplifier 108 is fed back in system 100 through another CMOS integrated circuit, represented by circuit block 102. Circuit block 102 represents a signal-analyzer integrated circuit, which is used for adaptive control of DPD operations of system 100.” [Col. 5, lines 62-66], and “The down-converted analog signal is converted into digital representation (i.e., digital signal 117) using ADCs 111.” [Col. 6, lines 2-4], and “RF feedback signal 115 is converted to analog in-phase and quadrature signals by quadrature down-converter 110 in signal analyzer integrated circuit 102” [Col. 8, lines 27-29], and “The output I/Q signals of quadrature down-converter 110 are converted to digital signals by ADCs 111” [Col. 8, lines 34-36]. Accordingly, RF feedback signal 115 corresponds to the claimed digitized analog signal correlated with the analog response produced by the transmit chain/power amplifier. It would have been obvious to one of ordinary skill in the art at the time of the invention to modify Megretski with the teachings of Yu to provide a digital representation of a feedback signal corresponding to the output response of the power amplifier for use in digital predistortion adaption and control, thereby improving characterization and compensation of transmit-chain behavior. Regarding Claim 56, Megretski discloses the limitations of claim 56 as recited above in the rejection of claim 55. In addition, Megretski further teaches, wherein combining the first and second signals using the nonlinear combiner includes combining the first signal with the digitized analog signal to generate the pre-distorted signal, “The actuator 200 predistorts the signal u to generate the predistorted signal v based , in part , on e” [Col. 12, lines 33-34], and “the actuator 120 is configured to perform the digital predistortion by using the time-varying control signal e in the digital predistortion of the input signal u” [Col. 14, lines 11-13], and “an actuator (predistortion) block that depends on both the signal itself and the envelope to thus use the envelope signal e (in addition to u) to generate the pre-distorted output v to the transmit chain” [Col. 8, lines 58-61], However, Megretski does not expressly teach, wherein the preprocessing includes translating the index signal to a digitized analog signal correlated with the analog response produced in the one or more components of the transmit chain. In the same field of endeavor, Yu teaches, wherein the preprocessing includes translating the index signal to a digitized analog signal correlated with the analog response produced in the one or more components of the transmit chain, “The output signal 115 of power amplifier 108 is fed back in system 100 through another CMOS integrated circuit, represented by circuit block 102. Circuit block 102 represents a signal-analyzer integrated circuit, which is used for adaptive control of DPD operations of system 100.” [Col. 5, lines 62-66], and “The down-converted analog signal is converted into digital representation (i.e., digital signal 117) using ADCs 111.” [Col. 6, lines 2-4], and “RF feedback signal 115 is converted to analog in-phase and quadrature signals by quadrature down-converter 110 in signal analyzer integrated circuit 102” [Col. 8, lines 27-29], and “The output I/Q signals of quadrature down-converter 110 are converted to digital signals by ADCs 111” [Col. 8, lines 34-36]. Accordingly, RF feedback signal 115 corresponds to the claimed index signal because it is the analog response generated by power amplifier 108 and fed back through the signal analyzer circuitry. Digital signal 117 corresponds to the claimed digitized analog signal because the down-converted analog response is converted into digital representation by ADCs 111. Thus, Yu teaches translating the claimed index signal into a digitized analog signal correlated with the analog response produced by the transmit chain. It would have been obvious to one of ordinary skill in the art at the time of the invention was made to modify Megretski with the teaching of Yu so that the signal used in digital predistortion processing includes a digital representation of a feedback signal corresponding to the output response of the power amplifier, thereby improving characterization of transmit-chain behavior and improving digital predistortion adaption and compensation accuracy. Regarding Claim 97, Megretski discloses the limitations of claim 97 as recited above in the rejection of claim 93. However, Megretski does not expressly teach, wherein translating the digital control signal comprises delaying the digital control signal. In the same field of endeavor, Yu teaches, wherein translating the digital control signal comprises delaying the digital control signal, “The memory-less non-linearity of block 201 is applied to a copy of the input signal delayed in delay element 202 by £ samples” [Col. 6, lines 24-27] It would have been obvious to one of ordinary skill in the art to modify Megretski’s translated digital control signal processing with Yu’s delayed-signal processing because Yu teaches using delayed signal versions in predistortion processing to compensate for memory effects and improve transmitter linearization performance. The modification would merely apply a known signal-processing techniques to Megretski’s predistortion architecture for its known purpose. Regarding Claim 99, Megretski discloses the limitations of claim 99 as recited above in the rejection of claim 93. However, Megretski does not expressly teach, delaying the RF signal to be transmitted or a translated version thereof with a delay circuit. In the same field of endeavor, Yu teaches, delaying the RF signal to be transmitted or a translated version thereof with a delay circuit, “FIG. 5 also shows complex gain and delay matching by finite impulse response (FIR) filter 503 a and integer delay circuit 503 b in the signal paths of RF feedback signal 115 and power amplifier input feedback signal 410, respectively.” [Col. 9, lines 58-61], and “ FIR filter 503 a includes a complex-coefficient FIR filter that provides, not only delay matching, but also linear distortion correction” [Col. 9, lines 62-64] It would have been obvious to one of ordinary skill in the art to incorporate Yu’s delay-circuit processing into Megretski’s predistortion system because Yu teaches that delay matching improves signal alignment and predistortion accuracy. Applying a known delay circuit to the RF signal path of Megretski would have predictably improved signal processing performance while using known techniques for their established purpose . 07-21-aia AIA Claim 53 is rejected under 35 U.S.C. § 103 as being unpatentable over Megretski et al. (US 10931238 B2, hereinafter “Megretski”), and further in view of Chandrasekaran (US 8711976 B2, hereinafter “Chandrasekaran”) Regarding Claim 53, Megretski discloses the limitations of claim 53 as recited above in the rejection of claim 52. In addition, Megretski further teaches, wherein the nonlinear combiner is configured to combine the first signal with the another signal to generate the pre-distorted signal, “The actuator also generates the signal e A , optionally based, in part, on the signal u” [Col. 12, lines 37-38], and “the new signal e A need not be based on the time-varying signal u, but instead may be, for example, a down-sampled version of the signal e, or may otherwise be a resultant signal processed (through some pre-determined filtering process) from the signal e.” [Col. 12, lines 45-49], and “The actuator 200 predistorts the signal u to generate the predistorted signal v based , in part , on e” [Col. 12, lines 33-34], and “an actuator (predistortion) block that depends on both the signal itself and the envelope to thus use the envelope signal e (in addition to u) to generate the pre-distorted output v provided to the transmit chain” [Col. 8, lines 58-61] However, Megretski does not expressly teach, preprocessing the second signal with a first preprocessing block to form a first preprocessed signal; preprocessing a third signal with a second preprocessing block to form a second preprocessed signal; and combining the first and second preprocessed signals with a third preprocessing block to form another signal. In the same field of endeavor, Chandrasekaran teaches, preprocessing the second signal with a first preprocessing block to form a first preprocessed signal, as shown in [FIG. 3], a first signal path includes Lookup Table f11 (3160 and Filter h1 (318), where the output of Lookup Table f11 (316) is processed by Filter h1 (318) to generate a processed signal. (see [FIG. 3]) preprocessing a third signal with a second preprocessing block to form a second preprocessed signal, as shown in [FIG. 3], a second signal path includes Lookup Table f21 (326) and Filter h2 (328), where the output of Lookup Table f21 (326) is processed by Filter h2 (328) to generate another processed signal. (see [FIG. 3]) combining the first and second preprocessed signals with a third preprocessing block to form another signal, as shown in [FIG. 3], the outputs of the multiple preprocessing path are provided to subsequent processing circuitry including Complex Multiplier 330 and are ultimately combined by Sum block 312 to generate output signal xpd[n]. Thus, Chandrasekaran teaches combining processed signals from multiple preprocessing signals from multiple preprocessing paths to form another signal that contributes to the predistorted output signal. (see [FIG. 3]) Which receives inputs from the signal paths associated with Filter h2 (328) and Lookup Table f21 (326), and produces an output signal that is supplied toward Sum block 312. [FIG. 3]. Thus, Complex Multiplier 330 corresponds to the claimed their preprocessing block that combines processed signal paths to form another signal. It would have been obvious to one of ordinary skill in the art at the time of the invention to modify Megretski with the teachings of Chandrasekaran because Chandrasekaran teaches multiple predistortion processing paths and combining the resulting processed terms using summation block 312. Applying Chandrasekaran’s known signal-processing architecture to Megretski would have predictably improved predistortion modeling and nonlinear distortion compensation.
