Abstract

Pilot interference cancellation (IC) has recently received consideration for use in third generation (3G) CDMA cellular receivers. In this paper, we derive an expression for evaluating the bit error rate (BER) performance of both the RAKE and pilot IC receivers, under conventional random spreading code assumptions. The approach can provide results for a wide variety of transmitter, channel, and receiver assumptions, and can easily take into account the effects of channel estimation, as used for determining the RAKE combining coefficients and for reconstructing pilot interference. The analytical results are compared to detailed link-level simulations of the 3G commercial wideband CDMA system developed by 3GPP, with excellent agreement found.
