Title:
ENCODING METHOD, DECODING METHOD, ENCODING DEVICE, AND DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/158031
Kind Code:
A1
Abstract:
The present application provides an encoding method, a decoding method, an encoding device, and a decoding device. The encoding method comprises: determining a parameter of a polar code according to the length K of information bits and/or a first target code length M of a first encoding sequence, wherein the parameter of the polar code comprises the code rate of the polar code or the code length M o of the polar code, the code rate of the polar code represents a ratio of K to M o , and K, M, and M o are positive integers; performing, according to the parameter of the polar code, polar encoding on the information bits of length K, so as to obtain a second encoding sequence of a second target code length M o ; performing low density parity check (LDPC) encoding on the second encoding sequence, so as to obtain the first encoding sequence of length M; and transmitting the first encoding sequence. Embodiments of the present application reduce instances of an error floor in LDPC codes.
