The invention discloses a
polar code encoding modulation method applicable to any high-order modulation. The method comprises the concrete steps of (1), calculating the code length of a
polar code; (2), generating an encoding matrix of the
polar code; (3), generating the encoding matrix after
puncturing; (4), generating code words of the polar code; (6)
interleaving the code words; and (7), carrying out high-order modulation. According to the method, the code words are interleaved by employing a grouping
interleaving technology, the polar effect of a channel is intensified with the combination of the polar characteristic of the polar code itself and the capacity differences of high-order modulation sub-channels, and the performance of the polar code is improved. According to the method, the encoding matrix is punctured according to a column weight, the decoding
delay is reduced, and the
programming realization complexity of a decoding
algorithm in a programmable device is reduced. The flexibility of the polar code in the high-order modulation is improved, and the polar code has good performance.
