WEIGHTED DECODING METHOD AND CIRCUITS FOR COMMA-FREE REED-SOLOMON CODES

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 for received Comma-Free Reed-Solomon symbol data, and the weighted symbol data is input 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 a decoding architecture that is based on a systolic array and the decoding architecture that is based on a folding systolic array.
