Title:
METHOD AND DEVICE FOR POLAR DECODING
Document Type and Number:
WIPO Patent Application WO/2019/041067
Kind Code:
A1
Abstract:
A method and device for polar decoding. The method comprises: obtaining a polar code sequence; determining at least one first information bit length corresponding to the code length of the polar code; and performing blind-detection-based decoding on the polar code sequence by using the code length and the at least one first information bit length, wherein the at least one first information bit length is a part of a preset information bit length set corresponding to the code length; the remaining part of the preset information bit length set is at least one second information bit length; the at least one second information bit length is excluded for blind detection, and each second information bit length is less than one or more information bit lengths in the at least one first information bit length. By applying the present solution to polar decoding, the complexity of blind-detection-based polar decoding is lowered.
