    Today's CDMA systems require high code rates to support high-speed/wide-band services, such as mobile multimedia services. A discrete time CDMA receiver, based on digital signal processing technology, needs several times higher sampling rates than its code rate, to minimize the performance degradation caused by code phase difference. In this paper, we suggest a low-sampling CDMA receiver, which minimizes the performance degradation caused by code phase difference using dual correlators. In addition, we analyze the SIR (Signal to Interference Ratio) performance of this receiver, based on the code phase difference, and perform computer simulations of the receiver's SIR performance to verify analytic results.
