摘要
Reed-Solomon (RS) codes have very broad applications in digital communication and storage systems. Among the decoding algorithms of RS codes, the Koetter-Vardy (KV) soft-decision decoding algorithm can achieve substantial coding gain with a polynomial complexity. One of the major steps of the KV algorithm is the interpolation. Recently, a new algorithm was proposed to solve the interpolation problem. Compared to previous efforts, this algorithm is computationally simpler, and thus can potentially lead to practical high-speed hardware implementations of the KV algorithm. This paper proposes novel transformation techniques to further reduce the hardware complexity of the new interpolation algorithm. In addition, efficient VLSI architectures are provided for the new algorithm.
