Abstract

The embodiment of the invention discloses a polar code decoding method and device, a decoder, equipment and a storage medium. The method comprises the following steps: acquiring S' surviving paths which are stored at present; storing S'' extension paths meeting a first selection condition in 2K * S' extension paths of the S' surviving paths, wherein K is a parallel decoding bit number, and K is greater than or equal to 1; selecting an extension path meeting a second selection condition from the S'' extension paths as a new surviving path; and updating the currently stored S' surviving paths by using the selected new surviving path.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and relate to but are not limited to decoding methods, devices, devices, and storage media of polar codes. Background technique [0002] In communication systems, channel coding is usually used to improve the reliability of data transmission to ensure the quality of communication. Polar codes (Polar codes) are a coding technique that has received increasing attention in recent years. By constructing composite channels and changing the characteristics of the original channel, the capacity of the composite channel is more close to the high and low poles. Due to this characteristic, polar codes can be adapted to randomly distributed original channels through appropriate coding design, and achieve good performance under many different channel implementations, and approach the channel capacity. Moreover, it can greatly reduce the complexity of the receiver through interference...
