Abstract

In this paper, an efficient implementation of the Chase II soft-input/soft-output (SISO) decoder using the distancebased decoding algorithm is proposed, where a piece-wise-linear based method is proposed to simplify the calculation of the extrinsic values. As a demonstration, a (64, 51, 6)^2 block turbo decoder is implemented. Compared to the DBD-based decoder presented in the previous literature, the proposed decoder achieves a higher throughput and a higher efficiency.
