Volterra Based Receivers for Ds-Cdma

Abstract

This paper presents a Volterra function based filter as the receiver for a direct-sequence-code-divisionmultiplex-access (DS-CDMA) system. The envisaged application would be cellular telephony, where the receiver will be required to be adaptive due to channel effects. The results obtained from the Volterra filter are compared against the linear minimum-meansquare-error (MMSE) filter and the nonlinear radialbasis-function (RBF) network in a stationary multipath channel. Further, the computational complexity will be investigated and compared against the MMSE.
