Abstract

The invention relates to the technical field of communication, and discloses a method for ranking the reliability of polarization channels, a polarization code coding method and a device thereof, which are used for improving the accuracy of ranking the reliability of polarization channels. The method comprises the following steps: determining the reliability of each of the N polarization channels,wherein the reliability of the ith polarization channel is based on a first distance spectrum between the first coset and the second coset, determining a second distance spectrum between elements within the first coset and a constant P related to a physical channel state, i belongs to {1, 2,..., N}, N is a mother code length of a polarized polar code, N=2m, m is a positive integer, and the firstcoset is based on a set 0th to (i-1) a sequence of decoded bits and a set of encoded codewords whose i-th decoded bits are determined to be 0, wherein the second coset is based on a set of 0 to (i; 1)a coded bit sequence and a coded codeword set determined that the i-th decoded bit is 1; and determining a reliability ranking sequence of the N polarization channels according to the reliability ofeach polarization channel of the N polarization channels.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method for sorting polar channel reliability, a polar code encoding method, and a device. Background technique [0002] As the most basic wireless access technology, channel coding plays a vital role in ensuring the reliability of data transmission. In existing wireless communication systems, generally, Turbo codes, low density parity check codes (low density parity check, LDPC) and polarization (Polar) codes are used for channel coding. Turbo codes cannot support information transmission with too low or too high a code rate. For the transmission of short and medium packets, Turbo codes and LDPC codes are difficult to achieve ideal performance under limited code length due to their own coding and decoding characteristics. In terms of implementation, Turbo codes and LDPC codes have high computational complexity in the process of encodi...
