Abstract

The invention discloses a method and a system for constructing a polar code with Bahathachia parameters. The method comprises the following steps: linearly merging and splitting bit information of preset coding length to get correlated bit channels; carrying out polarization operation on the bit channels to get Bahathachia parameters of the odd-numbered channels and the Bahathachia parameters of the even-numbered channels; sampling and extracting five parameter expressions according to a set corresponding to the Bahathachia parameters of the odd-numbered channels; carrying out polar code construction based on the five parameter expressions to get chain tables respectively corresponding to the five parameter expressions; and decoding the chain tables corresponding to the five parameter expressions according to an SCL-CRC algorithm, and acquiring the parameter expression with the lowest bit error rate and the lowest block error rate as a code construction parameter. Extremely low bit error rate and block error rate are obtained, and the lowest computational complexity is achieved.

Description

technical field [0001] The present invention relates to the technical field of channel coding, in particular to a method and system for constructing polar codes using Bahatacheya parameters. Background technique [0002] In the field of channel coding technology, reaching Shannon's limit capacity is the optimal solution. The performance of the previously proposed Turbo code and LDPC code is very close to Shannon's limit capacity, and these two coding techniques have been widely promoted and applied in the field of modern communication. However, there is still no reliable theory to prove that these two encoding techniques can reach the Shannon limit, and Turbo codes and LDPC codes still have the problem of high encoding and decoding complexity. [0003] Arikan finally used the concept of channel polarization in 2009 to propose an unprecedented coding technique - polar codes. This kind of coding is extremely analyzable, and the most important thing is that it has the characte...
