The performance of the DS/ CDMA system with the multibit quantization coherent receicer is analyzed. On the basis of the common DS/ CDMA model, the formula of bit error rate for the multibit quantization DS/ CDMA system is obtained by considering the effects of the quantization noise. The results are valuable to some extent for the design of the CDMA system based on the digital coherent matched filter.
