Abstract:This is the second part of a series of papers on a revisit to the bidirectional Bahl-Cocke-JelinekRaviv (BCJR) soft-in-soft-out (SISO) maximum a posteriori probability (MAP) decoding algorithm.Part I revisited the BCJR MAP decoding algorithm for rate-1 binary convolutional codes and proposed a linear complexity decoder using shift registers in the complex number field. Part II proposes a low complexity decoder for rate-1 non-binary convolutional codes that achieves the same error performance as the bidirection… Show more
