Bit dependence of the bit-by-bit decision is the main source of complexity and delay of the whole decoding system.Therefore,based on CRC-SCL decoding,a new decoding algorithm APC-SCL decoding algorithm is proposed.Through theoretical analysis and MATLAB simulation,the performance of decoding under the code length of 1024 is verified.Under the condition of the same search width the average search width of the APC-SCL decoding algorithm is reduced by 26.5% compared with the CRC-SCL decoding which reduces the system complexity.The algorithm is more effective in the low SNR interval.
