Algebraic soft decision decoding algorithm for Reed-Solomon codes based on Chase algorithm
Feng Guang-zeng · Journal of Circuits and Systems · 2009
To improve the error-correcting performance,an algebraic soft decision decoding(ASD) algorithm for Reed-Solomon(RS) codes based on Chase algorithm is proposed,called Chase-ASD,which can make full use of the reliabilities of the received bits with higher computation complexities.To reduce the computation complexities of the proposed algorithm,a simplified Chase-ASD algorithm is then presented.Simulation results show that both Chase-ASD and simplified Chase-ASD can provide more decoding gains over the original ASD algorithm.
