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 .
Priority
Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55.
Specification
The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification.
Claim Objections
Claims 3, 11, and 19 are objected to because of the following informalities:
Claim 3 (lines 7-8), claim 11 (lines 9-10), and claim 19 (line 7), the phrase “the decision region” should be “the first decision region”.
Claim 11, line 12, the phrase “a second positive” should be “a second positive sign”.
Appropriate correction is required.
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 17-20 are rejected under 35 U.S.C. 101 because “[A] computer-readable storage medium” recited in claim 17 and “[The] computer-readable storage medium” recited in the dependent claims 18-20 would appear to encompass both transitory and non-transitory media, such as a memory or storage device described in paragraph [0307] of the specification. Therefore, the broadest reasonable interpretation means the “computer-readable storage medium” includes a transitory medium such as a signal or waveform and therefore is non-statutory.
Allowable Subject Matter
Claims 1-2, 4-10, and 12-16 are allowed.
Claims 3 and 11 would be allowable if rewritten or amended to overcome the objection(s) set forth in this Office action.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Raphaeli et al. (US 2013/0064281 A1) relates to a decision feedback equalizer (DFE) in Figure 2 comprises a coefficient setting unit (225) for setting a first group of most significant feedback coefficients of the DFE to a predefined value selected from a group of predefined values; a coefficients computation unit (220) for computing values of feedback coefficients of a second group of feedback coefficients other than the first group of most significant feedback coefficients; a feedback (FB 210) unit for mitigating, using a complete group of feedback coefficients, effects of interference from data symbols that are adjacent in time to an input data symbol, wherein most significant feedback coefficients of the first group are set to an optimal value computed during an initialization of the DFE and feedback coefficients of the second group are computed by the coefficients computation unit, wherein the complete group of feedback coefficients include the first and second groups of feedback coefficients; a calibration module (260) for computing voltage levels of a PAM-N signal and for computing a value of a quality parameter utilized to determine the optimal value for the feedback coefficients in the first group of most significant feedback coefficients; and an error-and-decision unit (240) for at least computing an error value indicating the sum of errors of an input symbol of the input data symbol from optimal positions of the voltage levels of the PAM-n signal.
LU (US 2021/0044462 A1) relates to an error correction method and apparatus.
In an implementation of the first aspect, if an absolute value of a second decision signal is greater than (M−1), the method includes: determining a symbol location of the second decision signal whose absolute value is greater than (M−1) as a symbol location at which the burst error ends; and correcting the burst error in the second decision signal.
WO 2019105244 A1 relates to an error correction method and an error correction apparatus, and being capable of reducing DFE bit error rate and improving equalizing performance. The method comprising: acquiring a decision signal of a decision feedback equalizer DFE; acquiring at least one signal amongst an input signal, an equalized output signal, and a difference of the DFE, the difference being the difference between the power level of the decision signal and the power level of the equalized output signal; on the basis of the detection of at least one signal amongst the decision signal, the equalized output signal, and the difference, determining a symbol position where the burst error of the decision signal ends; and, when detecting the symbol position, on the basis of at least one signal amongst the input signal, the equalized output signal, and the difference, performing error correction on the decision signal.
CN 113055020 A relates to a burst error code detection method based on coding constraint. The method comprises: before decoding, performing hard decision on the decoding initial information; calculating the syndrome according to the hard decision result and the LDPC code check matrix; generating the error code indication sequence according to the associated type; constructing an initial search window for the generated error code indication sequence; counting the error code rate estimation value in the sliding window by means of sliding search, and comparing the error code rate estimation value with the preset threshold value; judging whether there is continuous burst error code; if there is continuous burst error, using bidirectional iterative window search method, determining the initial and ending position of the burst error code, according to the initial and ending position of the burst error code, calculating the length of the burst error code and deleting the corresponding channel information; and if there is no continuous burst error code, directly outputting the result after decoding.
CN 114448559 A relates to a position detection method and device to determine the position of a judgment signal starting from a burst error in a judgment signal sequence, and helps to eliminate an error at the starting position of the burst error. The method comprises: obtaining the position of the judgment signal at the end of a burst error in a judgment signal sequence of a decision feedback equalizer (DFE); and obtaining a first target numerical value corresponding to a first signal position in the judgment signal sequence, wherein the first signal position is the position of at least one decision signal before the decision signal of which the burst error ends. The first target value comprises at least one of a symbol value of a decision signal at the first signal position, a first equalization value corresponding to the first signal position, or a first difference value corresponding to the first signal position.
