An Adaptive Hybrid List Decoding and Chase-like Algorithm for Reed-solomon Codes

This paper presents an adaptive hybrid Chase-like algorithm for Reed-Solomon codes, which is based on the list decoding algorithm. The adaptive hybrid algorithm is based on the reliability threshold to exclude the more reliable bits from being processed by the list decoding algorithm and reduce the complexity of the hybrid algorithm. Simulation results show that the decoding complexities of the adaptive hybrid algorithm for both (15.7) and (31.21) Reed-Solomon codes are almost the same as those of the list decoding algorithm (without Chase algorithm) at high signal-to-noise ratios, but there is a significant improvement in FER performance.
