Claim 0:
1. An encoding method performed by an encoder, the method comprising:
obtaining a first matrix as an m-fold Kronecker product of a 2×2 binary lower triangular matrix, where m=log 2(M/2), M<N, and N is the length of a polar code to be generated;
obtaining a second matrix of dimension 2S×2S, where S=N/M and an inverse of the second matrix is a lower triangular band matrix;
generating a transformation matrix for the polar code by calculating a Kronecker product of the second matrix with the first matrix;
determining an information set I identifying reliable bit channels for the polar code;
obtaining a polar codeword of length N using the polar code; and
transmitting a transmission signal comprising the polar codeword to a receiving device.
