Title:
LSC-CRC DECODING-BASED SEGMENTED POLAR CODE ENCODING AND DECODING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/133215
Kind Code:
A1
Abstract:
Disclosed in the present invention are an LSC-CRC decoding-based segmented polar code encoding and decoding method and system. The method comprises: performing combining and splitting operations on multiple independent channels to obtain the same number of bit channels as the number of the independent channels, acquiring a capacity of each of the bit channels, and performing computation to acquire the number of fully polarized bit channels; dividing, according to the number of the fully polarized bit channels, a free information bit sequence to be transmitted into a corresponding number of sub-sequences, performing polar coding on each of the sub-sequences, and sending the encoded information in the corresponding bit channels; and receiving the encoded information at a receiving end, performing, according to an LSC-CRC decoding algorithm, decoding segment by segment, and joining decoded sub-sequences obtained from the decoding in a head-to-tail manner to obtain a decoded sequence. The channel encoding and decoding method of the present invention enables simple operation, lowers spatial complexity of encoding and decoding, and improves decoding accuracy.
