Problems solved by technology

The distance spectrum is the spectrum formed by the number of codewords of each Hamming distance. However, in the process of actually analyzing the distance spectrum, in order to ensure the accuracy of the analysis of the distance spectrum, a larger serial offset list is generally used, and the serial The list used by the row offset list decoding algorithm is too large, which will lead to high computational complexity when analyzing the distance spectrum

Abstract

The embodiment of the invention provides a polar code distance spectrum analysis method and device, and relates to the technical field of communication. The method and the device simplify the polar code distance spectrum analysis method on the premise of ensuring the accuracy. According to the scheme of the embodiment of the invention, the method comprises the steps: determining an initializationtransmission parameter of a polarization code, determining the minimum Hamming distance of the polarization code according to the initialization transmission parameter of the polarization code, searching a code word with the Hamming distance being the minimum Hamming distance through a depth-first search method by taking the minimum Hamming distance as a search radius, and analyzing the distance spectrum of the polarization code.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for polar code distance spectrum analysis. Background technique [0002] Polar code is a forward error correction coding method, which is used for signal transmission. It can be used as the only channel coding technology that can be theoretically proven to reach the Shannon limit and has practical linear complexity coding and decoding capabilities. Among them, the Shannon limit refers to the maximum transmission rate for error-free transmission on a channel with random bit errors, and the maximum likelihood decoding performance of polar codes can be evaluated by the distance spectrum. [0003] At present, the polar code distance spectrum analysis method is based on the serial cancellation list decoding algorithm. This method transmits all 0 codewords at a high SNR, and uses a serial cancellation list decoding algorithm with a very large list at ...
