The invention provides 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 the following steps: performing gain amplification and sampling on a communication signal, and identifying a leadingpart x1(i) in the communication signal; setting an amplification gain G2 of the controllable gain circuit according to the effective leading signal T1(i) and other interference signal parts N1(i); subsequently, enabling the communication signal comprising the load data to pass through an amplification gain G2 of a controllable gain circuit and sampling, and performing frequency interference suppression processing on communication signal sampling data x2(i) to obtain a signal y2(i) after frequency interference suppression; further calculating a signal z2(i) after pulse interference suppression; and further sending the
