Reed Solomon

Implementation of a Reed-Solomon decoder using RiBM, Chien search, and modified Forney's algorithm.RiBM algorithm: (Reformulated inversionless Berlekamp-Massey) see "High-Speed Architectures for Reedd-deOCtSolomon Decoders" by Dilip V. Sarwate, and Naresh R. Shanbhag, IEEE Transactions on Very...

Format of Reed-Solomon CodesThe basic building block of Reed-Solomon codes is a symbol composed of m binary bits, where m can be any natural number greater than 2. For a given m, the length of all the Reed-Solomon codes composed of m-bit symbols is 2m - 1. For example, for 8-bit symbols, the...
