Title:

LDPC ENCODING METHOD AND DEVICE FOR COMMUNICATION SIGNAL

Document Type and Number:

WIPO Patent Application WO/2019/120119

Kind Code:

A1

Abstract:

The present application provides an LDPC encoding method and a device for a communication signal, for reducing encoding complexity. The encoding method comprises: acquiring an (N-M) × 1 information bit vector I(x) according to information bits of a communication signal to be sent; acquiring a check set vector D(x) according to I(x) and an M × (N-M) system partial matrix N(x), where D(x) meets the following condition: D(x) = {N(x) I(x)} mod 2; determining an M × M check partial matrix M(x), wherein M(x) is a bidiagonal matrix, a polynomial matrix Q(x) corresponding to a first column vector of M(x) is represented as Q(x) = I + x ah + x bh , Q -1 (x) = x -2×β×h Q(x), a and b are different constants, h = 2 j-1 , and β and j are positive integers; determining, according to D(x) and M(x), a check bit vector C(x) corresponding to I(x), where C(x) meets the following condition: D(x) = {M(x) C(x)} mod 2; and generating, according to I(x) and C(x), a code word corresponding to the communication signal to be sent.
