摘要：

In this paper, a new DS-CDMA Rake receiver architecture is proposed. Unlike the conventional receiver, the proposed SigmaDelta-CDMA receiver does not require a SigmaDelta demodulator and a root-raised-cosine (RRC) filter, and hence its despreader can be implemented mainly using simple XNOR gates and 2-bit adders. The conditional BER for DS-CDMA forward link is derived and the averaged BER is obtained by Monte Carlo simulation. It is shown that the BER performance of the proposed receiver can match that of the conventional DS-CDMA receiver, which is implemented using a SigmaDelta analog-to-digital convertor (ADC), with the proper choice of over-sampling ratio. And the proposed receiver achieves a much smaller gate-count than the conventional receiver when implemented on FPGA.
