AI Technical Summary

Technical Problem

During the encoding and decoding process of existing LDPC codes, as the encoding length increases, the design of improving factor sets and translation value sets cannot guarantee stable encoding and decoding performance.

Method used

The check matrix is ​​determined to optimize encoding and decoding performance by designing a set of boosting factors based on multiple sets of prime and non-exponential forms.

Benefits of technology

The shortened number of bits is avoided to increase exponentially with the increase in encoding length, and more stable encoding and decoding performance is achieved.

Abstract

The present application relates to a communication method, a communication device, a communication apparatus, and a computer-readable storage medium. The method comprises: on the basis of the length of an information bit sequence and a basic matrix, determining a lifting factor from a lifting factor set, wherein the lifting factor set comprises a prime number and a multiple set associated with the prime number, or the lifting factor set comprises a plurality of lifting factors, the lifting factor among the plurality of lifting factors is a product of a multiple in the multiple set associated with the prime number and the prime number, the multiple in the multiple set is a positive integer, and the multiple set comprises values not equal to Ax, wherein A is a positive integer equal to or greater than 2, and x is a non-negative integer. The method further comprises: on the basis of the lifting factor and the basic matrix, determining a check matrix, wherein the check matrix is used for encoding or decoding the information bit sequence.
