摘要：
A digital signal processor performs despread decoding in wireless telephone systems. Orthogonal codes are used to combine data signals into one overall coded signal which is transmitted. The orthogonal codes are used to retrieve individual data signals from the transmitted overall coded signal. Despread instructions are included in the digital signal processor functionality.
