Embodiments of the present invention provide a generation method and a generation device for mixed polar code. The method comprises: obtaining a first matrix being &Ngr;×&Ngr; and a sequence comprising N bits, N being the code length of the mixed polar code, N rows of the first matrix corresponding to N bits in the sequence, and N being a positive integer; determining the reliability of the N bits and determining the weight of the N rows of the first matrix; according to the reliability of the N bits and the weight of the N rows of the first matrix, selecting K bits, acting as information bits, from the N bits or selecting K rows of the first matrix to form a second matrix being K×N and for coding, so as to perform coding on an information bit sequence according to the position of the information bits or according to the second matrix to generate the mixed polar code, K being the length of the information bit sequence to be coded and being not greater than N. The embodiments of the present invention not only take the reliability into account, but also take the weight of the corresponding row of the first matrix, thereby improving the performance of the polar code. |
