Problems solved by technology

However, the existing Polar code punching method is only suitable for the case where the number of punched holes is small. When the number of punched holes is large, the performance gap with the non-punched Polar code is large, and it is not robust in complex electromagnetic environments.

Abstract

The present invention provides a polar code punching method, device, electronic equipment, and storage medium, including: obtaining a polar code; determining the code length of the parent polar code based on the polar code; The number of hole layers, determine the number of punched holes in each sub-layer; calculate the Bhattachary parameter of each channel of each sub-layer, and determine the punching pattern of the corresponding sub-layer based on the Bhattachary parameter of each channel; after obtaining each sub-layer After the puncture pattern of each sublayer is merged as the final puncture pattern of the polar code, the puncture is performed based on the final puncture pattern of the polar code. The present invention utilizes the characteristics of the matrix generated between each level of the polar code, divides the polar code punching into multi-layer punching, reduces the number of punching holes in each layer, and realizes smaller coding performance loss by layer-by-layer coding , thereby improving the situation that the reliability of the communication system decreases and the loss of coding gain is large due to the large number of punching holes, and thus has the advantages of large coding gain and low complexity.

Description

technical field [0001] The present invention relates to the technical field of digital signal processing, in particular to a polar code punching method, device, electronic equipment and storage medium. Background technique [0002] The complex electromagnetic environment is highly time-varying, and the real-time channel conditions and system platform resources will change at any time. Therefore, the parameters (code length and code rate) of the channel coding in the communication system are required to be flexible and variable. However, the polar code (Polar code) itself uses the combination and splitting of two channels to realize the polarization phenomenon. Its coding rules determine that the code length of the Polar code is an integer power of 2, which can be obtained by using the standard Polar code The hole punching implements rate matching. However, the existing Polar code punching method is only suitable for the case where the number of punched holes is small. When ...
