Abstract
The present invention provides a coding method and a coding device. The coding method includes: coding information bits a to be coded via cyclic redundancy check CRC, then inputting the bits coded via the CRC into an interleaver determined by a construction parameter of a Polar code, where the interleaver is configured to interleave the bits coded via the CRC and output interleaved bits; and coding the output interleaved bits via the Polar code to obtain a coded Polar code. The above method is used to solve a problem in the prior art that minimum code distance of a Polar code is not large enough when the Polar code is relatively short or is of a medium length.

A coding method, comprising:
- coding information bits to be coded via cyclic redundancy check CRC, then inputting the bits coded via the CRC into an interleaver determined by a construction parameter of a Polar code, wherein the interleaver is configured to interleave the bits coded via the CRC and output interleaved bits;
- and
- coding the output interleaved bits via the Polar code to obtain a coded Polar code.
A coding device, comprising:
- a CRC check module, configured to code information bits to be coded via cyclic redundancy check CRC;
- an interleaver, configured to interleave the bits coded via the CRC to obtain interleaved bits;
- and
- a Polar code coding module, configured to code the interleaved bits via the Polar code to obtain a coded Polar code.
