Abstract

The invention discloses a decoding method and device, and belongs to the technical field of communication. The method comprises the following steps: receiving a to-be-decoded sequence; determining a plurality of decoding sequences according to the code length of the to-be-decoded sequence, each decoding sequence being used for indicating a sequence in which a plurality of bits corresponding to theto-be-decoded sequence are decoded; and decoding the to-be-decoded sequence in parallel according to various decoding sequences, and outputting a decoded bit sequence. According to the invention, multiple decoding sequences are determined according to the code length of the to-be-decoded sequence. Then, the to-be-decoded sequence is decoded according to the multiple decoding sequences at the sametime. Thus, a plurality of bits can be decoded at the same time in some decoding time slots, so that the time slots required for completely decoding the plurality of bits corresponding to the to-be-decoded sequence are reduced, the decoding time is shortened, and the decoding efficiency is improved.

Description

Technical field [0001] This application relates to the field of communication technology, and in particular to a decoding method and device. Background technique [0002] In recent years, the research on the decoding of polar codes has become a hot issue in the communication field. At present, the decoding methods of the sequence to be decoded are mainly divided into two types: sequential decoding and non-sequential decoding. Among them, time sequence decoding refers to decoding bit by bit according to the sequence 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 to be decoded Y N After that, you can first according to Y N Translate the first bit U 1 . After that, according to Y N And U 1 Decode, get the second bit U 2 . Get U 2 After that, according to Y N , U 1 And U 2 Decode, get the third bit U 3 . And so on, unt...
