Abstract:
In this paper we introduce a new approach of turbo decoding for parallel concatenated codes based on one-step majority logic decodable codes. This approach uses a soft-input soft-output threshold decoding algorithm as component decoder. Numerical results for parallel concatenated codes transmitted over Additive White Gaussian Noise (AWGN) channel are provided. We also present a comparison between our results and those of Lucas et al. in terms of BER performance.
