DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Bai – US 2013/0343483 in view of Ghannouchi et al. – US 2023/0268942.
Re claim 18, Bai discloses:
“actuator circuitry configured to perform a digital predistortion (DPD) operation using at least one of multiple neural networks associated with respective nonlinear characteristics of a nonlinear component of the RF transceiver, the multiple neural networks comprising” (Fig. 1, 2; elements 26, 36; para. 0025, 0029, 0034; Abstract; wherein Bai compensates for distortion introduced by a non-linear device and the artificial neural network (ANN)- based model comprises “multiple networks” as interconnected group of signal processing elements referred to as artificial neurons, ANs),
“a first neural network for state estimation of a nonlinear component of the RF transceiver based on an input signal to the nonlinear component and a feedback signal indicative of an output of the nonlinear component, the feedback signal formed from looping the output of the nonlinear component back from a transmitter path to a receiver path in the RF transceiver” (para. 0035-0037 wherein at least some of the ANs model the device’s distortion using the input and output (feedback)), and
“a second neural network for prediction of a state of the nonlinear component based on a second input signal of the nonlinear component (para. 0036, 0038; where at least some of the ANs model the predistorter’s response corresponding to the desired output (i.e. “predict”).
Bai differs from the claimed invention that it does not explicitly disclose the above underlined claimed subject.
Ghannouchi, in similar field of endeavor, teaches the above underlined claimed subject matter in a transceiver at a base station, that utilizes DPD model for mitigating the nonlinearity from nonlinearity component, including use of neural network (para. 0019) that provides feedback loop from the transmitter chain to the receiver chain in the transceiver for adapting the DPD (Fig. 3a; para. 0002, 0004, 0019, 0053, 0064, 0071, 0073).
Therefore, it would have been obvious to a person of ordinary skill in the art at the time of the filing to have incorporated such teaching from Ghannouchi, into the base station of Bai to provide even more accurate adaptation for the DPD modeling.
Allowable Subject Matter
Claims 1-17, 19-21 are allowed.
Response to Arguments
Applicant’s arguments with respect to claim(s) 18 have been considered but are moot because the new ground of rejection does not rely on reference applied in the prior rejection of record for teaching or matter specifically challenged in the argument.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
