Abstract

The application discloses a decoding method and device, which belong to the technical field of communication. The method includes: receiving the sequence to be decoded; determining a variety of decoding sequences according to the code length of the sequence to be decoded, each decoding sequence is used to indicate one of a plurality of bits corresponding to the sequence to be decoded Sequence: According to multiple decoding sequences, the sequence to be decoded is decoded in parallel, and the decoded bit sequence is output. In this application, various decoding sequences are determined through the code length of the sequence to be decoded. Afterwards, the sequence to be decoded is simultaneously decoded according to multiple decoding orders. In this way, in some decoding time slots, multiple bits can be decoded at the same time. In this way, the time slots required for decoding all the bits corresponding to the sequence to be decoded are reduced, which shortens the decoding time and improves the decoding efficiency. code efficiency.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a decoding method and device. Background technique [0002] In recent years, the decoding of polar codes has become a hot topic in the field of communication. At present, the decoding methods of the sequence to be decoded are mainly divided into two types: sequential decoding and non-sequential decoding. The sequential decoding refers to decoding bit by bit according to the timing of the sequence to be decoded. [0003] The current main timing decoding method is the successive cancellation (Successive Cancellation, SC) decoding method. In this decoding method, after receiving the sequence Y to be decoded after being interfered by noise N After that, you can first base on Y N Decode the first bit U 1 . Afterwards, according to Y N and U 1 Decode to get the second bit U 2 . in getting U 2 Afterwards, according to Y N , U 1 and U 2 Decode to get ...
