In this paper, a novel non-phase-based frequency acquisition method for MDPSKDS/CDMA receiver is presented, which has fast ac-quisition speed, wide acquisition range and low imple-mentation complexity. The performance of the pro-posed method is evaluated over the AWGN channeland compared with that of the phase-based method.
