- 초록
- In this paper, we have evaluated the BER performance of an asynchronous DS/CDMA BPSK system using a conventional receiver under impulsive noise environments, and have proposed a selective hard limiting(SHL) receiver in order to compensate for the performance degraded by the impulsive noise. As a result, we show that, under impulsive noise environment, the performance of the proposed receiver is much better than that of the conventional CDMA receiver or the hard limiting CDMA receiver. Hence, we can conclude that the SHL receiver proposed in this paper is an effective CDMA receiver in sense of capability to overcome the impulsive noise environments. © Springer-Verlag Berlin Heidelberg 2003.
