Polar coding is a code construction method that can achieve the capacity of symmetric binary-input discrete memoryless channels (B-DMC).Polar codes in standard form are non-systematic polar codes (NSPCs).The codes are susceptible to error propagation under successive cancellation (SC) decoding while systematic polar codes (SPCs) are more robust against error propagation.SPCs may be considered as a generalization of NSPCs.Here，we demonstrate the performance advantages of SPCs over NSPCs under SC decoding.
