【Abstract】 Concerned in this paper is a direct sequence spread spectrum multiple access communication system based on residue number system. The system activates in a multipath fading channel, and a RAKE receiver structure with maximum ratio combination is used for demodulation. Approximation to the error probability is given and compared that of the direct sequence spread spectrum communication system with the M array orthogonal modulation scheme.更多还原
