Iterative demodulation of orthogonal signaling formats for DS-CDMA Conference Paper uri icon

abstract

  • Iterative schemes for demodulating M-ary orthogonal signaling formats in direct-sequence code-division multiple access (DS-CDMA) systems are proposed and compared with the standard matched filter receiver and the standard parallel interference cancellation (PIC) receiver. The considered system is similar to the uplink (reverse link) of an IS-95 system. The channel is assumed to be a time-varying flat Rayleigh-fading channel, and a channel estimation scheme is proposed. The proposed receivers are shown to provide large capacity gains compared with the conventional receiver.
