Abstract

The invention discloses a polarization code belief propagation decoding method and device, and a storage medium. The method comprises the following steps: carrying out belief propagation decoding on information received by a decoder; judging whether a decoding result of the belief propagation decoding meets a judgment condition or not, if so, stopping executing the belief propagation decoding, andotherwise, generating an overturning set based on the decoding result; performing flip-based decoding according to the flip set. According to the method disclosed in the invention, the error correction performance of the list decoding method and equipment can be continuously eliminated while the high decoding throughput rate is achieved, and soft information can be iteratively output; thus co-architecture design of joint detection decoding, LDPC and polarization codes becomes possible.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a polar code belief propagation decoding method, device and storage medium. Background technique

[0002] Mobile communication has experienced the development process from the first generation analog communication (1G) to the fourth generation mobile communication (4G), and has now entered the application stage of the fifth generation mobile communication (5G) industrialization. 5G proposes three application scenarios, including enhanced mobile broadband (eMBB), ultra-low-latency highly reliable communications (URLLC) and massive machine-type communications (MMTC) scenarios, respectively requiring high-speed, low-latency, high-reliability and high-speed Application requirements for connection density.

[0003] Channel coding is one of the important components of the communication system, and its function is to improve the transmission reliability of digital signal...
