Xiu-zhi Yang, Bing Song, Lin-huang Wu · 2010
This Reed-Solomon(RS) code with perfect error-correcting performance is one of the most important technologies for Mobile Multimedia Transmission. In this paper, Improved Berlekamp-Massey(BM) algorithm is adopted in the research of RS decoder. According to the features of FPGA hardware, Galois field multiplier with constant coefficients is used in implementing RS decoder on FPGA. The hardware complexity of RS decoder is reduced and the decoding speed is enhanced.
