摘要 提出了一种新型的高数据吞吐率RS解码器,它采用无除法Berlekamp-Massey,Chien和Forney等算法实现。该解码器采用一种新型的结构化复接流水线结构,具有很高的效率和突出的吞吐能力。根据设计实现的解码器性能,该解码器相比现有的解码器具有显著的吞吐率增益。 Reed-Solomon (RS) coding is one of the most widely applied channel coding schemes. Due to the increasing speed and throughput of communication systems, high-throughput RS-coded systems are intensively required. A novel highthroughput RS decoder was derived and proposed. Inversion-free Berlekamp-Massey, Chien, and Forney algorithms were adopted in the decoder. The proposed decoder featured a new efficient multiplexing pipeline, which provided considerable throughput-performance improvement. As shown in implementation results, the proposed decoder renders significant throughput enhancement regarding hardware complexity, compared with other known RS decoders.
