An improved CRC calibration in power communication

Aiming at the problem of check miss rate in CRC check in power communication, this paper adopts the method of parallel packet check to select the optimal number of packets while reducing the missed check rate of CRC check. Firstly, by analyzing the CRC calibration algorithm, the error detection ability of the algorithm is obtained, and then, through the method of mathematical proofs, a new method to reduce the transmission of BER is proposed; Secondly, because the end uses a parallel check circuit, this circuit introduces a new problem while reducing the check time. Although using parallel packet verification can reduce time, it also consumes more hardware resources at the same time, and high requirements may lead to new interference and error detection problems; Thirdly, through experimental analysis, the optimal number of subgroups is selected.
