An efficient siso algorithm for reed-solomon codes
Vishakan Ponnampalam, Alex J. Grant · 2003
There has been renewed interest in iterative decoding algorithms for concatenated codes since the introduction of Turbo codes. Such iterative methods are built on top of soft-insoft -out algorithms. Powerful concatenated codes may be constructed with linear block codes codes as constituent codes. Such codes can be better alternatives to Turbo Codes either when high coding rates or when short interleaver lengths are required. This paper presents a computationally efficient maximum a-posteriori (MAP) soft-in-soft-out (SISO) algorithm for RS codes and related codes.
