Title:
POLAR CODE SEGMENTED FLIPPING DECODING METHOD BASED ON LLR, AND INTELLIGENT TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/000531
Kind Code:
A1
Abstract:
Disclosed are a polar code segmented flipping decoding method based on an LLR, and an intelligent terminal. The method comprises: calculating an LLR value of an information bit channel, performing statistics on index distribution of a low-reliability channel, and determining segmenting positions; performing segmented coding on an information sequence according to the segmenting positions, and then sending the information sequence to a transmission channel; performing SCL decoding on the received sequence, and performing a CRC in a segmented manner; performing bit flipping decoding on a sub-code segment that does not pass the CRC; and if the flipping decoding succeeds, continuing to decode the next segment or outputting a decoding result, and if the flipping decoding fails, terminating the decoding and declaring that the decoding has failed. According to the LLR-based segmented decoding in the present invention, multi-bit flipping decoding is realized, and the error correction success rate is improved; failed decoding is terminated in a timely manner, and calculation complexity is reduced; and a better decoding performance can be realized with lower calculation complexity.
