The soft-limiting and blanking correlators are proposed for DS/SSMA BPSK nonlinear correlation receivers and when the addaptive white Gaussian noise and impulsive noise are induced and multiple access interference is occured, the performance of soft-limiting and blanking correlation receivers are analyzed. In this paper, asymtotic error probability is used for performance evaluation. For the accuracy of analysis, average bit-error probabilities are computed via Monte Carlo simulations for linear, hand-limiting, soft-limiting, and blanking correlation receivers in both single-and two-user impulsive channels. In multi-user case, the near-far problems on the performances of soft-limiting and blanking correlation receivers in an impulsive channel are considered.
