The invention particularly relates to a coding method for assisting a polarization code by using a CRC code and a PC code together. The invention belongs to the technical field of channel coding, and in the method, a CRC (Cyclic Redundancy Check) code with relatively high error detection efficiency is added into a PC-polar code assisted by a parity check code, and a check function of the PC code is optimized through different numbers and positions of the PC code and a five-bit cyclic shift register, so that the error correction performance of the PC-polar code is obviously improved. A simulation result shows that when the block error rate (BLER) of the CRC-PC-polar (CRC8, PC6) code constructed by the algorithm is 10<-5>, compared with a PC-polar code, a cyclic redundancy check polar code and a segmented cyclic redundancy check polar code, the CRC-PC-polar (CRC8, PC6) code constructed by the algorithm has net coding gains of 0.4 dB, 0.1 dB and 0.2 dB respectively. 本发明具体涉及一种利用CRC码与PC码共同辅助极化码的编码方法。本发明属于信道编码技术领域，
