Problems solved by technology

[0007] In this case, at the decoding end, it is necessary to obtain the estimate of the information bits in the received Polar code sequence before performing the CRC check, especially in the decoding process based on the SCL decoding algorithm. The estimation of multiple paths is obtained, that is, the CRC check can only be performed after obtaining the information bits in each path, which greatly increases the delay of the decoding process and affects the user experience

Abstract

The invention provides a polarization code coding method, a decoding method, a coding device and a decoding device. The coding method comprises the following steps: a coding device generates a first bit sequence according to target information needing to be transmitted to a decoding device, wherein the first bit sequence includes information bits and fixed bits, and the information bits are used to carry the target information, and the fixed bits are used to carry preset information; the coding device determines a check bit according to the first bit sequence; the coding device generates a second bit sequence according to the first bit sequence and the check bit; and the coding device generates a polarization code sequence according to the second bit sequence. Decoding delay can be reduced, and the user experience can be improved.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a coding method, a decoding method, a coding device and a decoding device of a polar code. Background technique [0002] Communication systems usually use channel coding to improve the reliability of data transmission and ensure the quality of communication. Among them, Polar codes are the first good codes that can obtain Shannon capacity and have low encoding and decoding complexity theoretically. [0003] With the aid of cyclic redundancy check (CRC, Cyclic Redundancy Check), the enhanced traditional serial cancellation (SC, Successive Cancellation) decoding algorithm is adopted, for example, the serial cancellation list (SCL, Successive Cancellation) obtained based on the improvement of SC algorithm List) decoding algorithm, serial cancellation stack (SCS, SuccessiveCancellation Stack) decoding algorithm and serial cancellation hybrid (SCH, Successive Cancellation H...
