Method and apparatus for encoding and decoding using Polar Polar code

摘要

Embodiments of the present invention disclose a method and apparatus for encoding and decoding using Polar Polar code. The decoding method includes: receiving by the receiving side Polar Polar code and indication information transmitted by the transmitting side; indicating that the length of the Polar Polar code is N; and Polar Polar code Determining the number L of surviving paths of the Polar Polar code according to the code length N of the code and the signal-to-noise ratio SNR for receiving the Polar Polar code, where L is a positive integer, Performing sequential erasure list SCL decoding on the Polar Polar code according to the number L of surviving paths to obtain L surviving paths, and at least one of L surviving paths of the decoding result of the Polar Polar code Checking and obtaining one. The present invention can address the shortcomings of the prior art that decoding is quite complex, as the number L of surviving paths is constant for the decoding of Polar codes.
