Abstract

The invention discloses a method for data transmission by using multivariate polar codes. probability, the upper limit of the error probability of the combined multiple channels is obtained; the K channels with the smallest upper limit of the error probability in the combined multiple channels are used to transmit information bits; The number is controllable, so that the complexity of coding during data transmission can be controlled. Since multi-polar codes are used, information loss during high-order modulation and demodulation can be reduced.

Description

technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and device for data transmission using multi-polarization codes. Background technique [0002] Communication systems usually use channel coding to improve the reliability of data transmission and ensure the quality of communication. Recently, the polar code (English: Polar Code; abbreviation: Polar code) proposed by Arikan is the first theoretical proof that Shannon capacity can be obtained and has low encoding and decoding complexity (the encoding and decoding complexity is O(NlogN), where N is a good code of code length). When the code length is short, the performance of traditional successive cancellation decoding (English: Successive Cancellation Decode; abbreviation: SC decoding) does not exceed the performance of low density parity check code (English: Low Density Parity Check Code; abbreviation: LDPC) code) and Turbo code. The latest research show...
