Abstract

The application relates to the technical field of communications, and discloses an encoding method and an encoding device for a Polar code for improving reliability calculating and ranking accuracy ofa polarization channel. The method comprises the steps of: acquiring a first sequence for encoding K bits to be coded, wherein the first sequence contains sequence numbers of N polarization channels,the sequence numbers of the N polarization channels are arranged based on the reliability of the N polarization channels in the first sequence, K is a positive integer, N is the mother code length ofthe Polar code and is a positive integer power of 2, and K is not greater than N; selecting sequence numbers of K polarization channels from the first sequence according to the order of reliability from high to low; placing the bits to be coded according to the selected K polarization channel numbers, and performing Polar code encoding on the bits to be coded.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a polar code encoding method and device. Background technique [0002] As the most basic wireless access technology, channel coding plays a vital role in ensuring the reliability of data transmission. In an existing wireless communication system, generally, Turbo codes, low density parity check codes (low density parity check, LDPC) and polarization (Polar) codes are used for channel coding. Turbo codes cannot support information transmission with too low or too high a code rate. For the transmission of short and medium packets, Turbo codes and LDPC codes are difficult to achieve ideal performance under limited code length due to their own coding and decoding characteristics. In terms of implementation, Turbo codes and LDPC codes have high computational complexity in the process of encoding and decoding. Polar codes are theoretically p...
