SUMMARY
Using list decoding and sequential decoding, PAC codes always show better performance than polar codes with the same blocklength. The typical approach is to add CRC redundant bits at the end of the information bits before PAC encoding, forming a CRC-PAC concatenated coding scheme. There are some attempts to concatenate CRC codes and PAC codes to improve decoding performance, where the application of the CRC-aided list (CA-List) decoding algorithm to CRC-PAC codes is further discussed. Simulation results show that the CRC-PAC codes can also approach the random-coding union . . .
