Abstract

An adaptive receiver with enhanced interference rejection is proposed for CDMA communications over multipath channels. The design of the receiver involves a two-stage procedure. First, an adaptive correlator bank is constructed in the form of generalized sidelobe canceller (GSC) to suppress strong interference. To reduce complexity, the partially adaptive implementation is incorporated in the design of GSC blocking matrix. Next, a maximum ratio combining of the correlator outputs is performed to constructively collect the multipath energy. Since strong MAI has been removed, channel estimation can be done accurately, leading to improved performance compared to the conventional RAKE receiver.
