Weighted decoding method and circuits for comma-free reed-solomon codes

摘要

A weighted decoding method and circuits for Comma-Free Reed-Solomon codes that apply to a cell search in a wideband code division multiple access system. The invention also provides a weighted decoding method wherein the decoding result of the secondary synchronization code is used as a weight, and the weight is added to the processing element array of the decoding circuit, so as to perform a weighted correlating comparison and thus enhance the accuracy of the decoding result. The weighted decoding method put forward by the invention may apply to the decoding architecture that is based on a systolic array and the decoding architecture that is based on a folding systolic array.
