Title:
METHOD AND CIRCUIT FOR SUPPRESSING PULSE INTERFERENCE IN CODING AND DECODING COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/258599
Kind Code:
A1
Abstract:
Disclosed are a method for suppressing pulse interference in coding and decoding communication, and a circuit for suppressing pulse interference in coding and decoding communication. The method for suppressing pulse interference in coding and decoding communication comprises: performing gain amplification and sampling on a communication signal, and recognizing a preamble part x1(i) of the communication signal; according to a valid preamble signal T1(i) and other interference signal parts N1(i), setting an amplification gain G2 of a controllable gain circuit; a subsequent communication signal which comprises load data being subjected to amplification processing of the amplification gain G2 of the controllable gain circuit and being sampled; performing suppression processing of frequency interference on sampled data X2(i) of the communication signal, so as to obtain a signal y2(i), the frequency interference of which is suppressed; then calculating a signal z2(i), the pulse interference of which is suppressed; and the signal z2(i) further being sent to subsequent decoding demodulation processing, so as to finally obtain the load data.
