Abstract

The adaptive successive interference canceler (ASIC) is a multistage nonlinear detector that sequentially estimates multiple users in a direct-sequence code-division multiple-access (DS/CDMA) system. In order to successfully regenerate the multiple access interference and subtract it from the received signal, the ASIC requires accurate estimates of the users´ received amplitudes. In this paper, we analyze the bit-error-rate performance of the ASIC employing a single antenna element in a synchronous DS/CDMA system. Computer simulations verify the accuracy of the analysis, and a numerical example illustrates the sensitivity of the SIC to incorrect amplitude estimates
