Abstract :
The performance analysis of a RAKE receiver for low processing gain DS/CDMA systems is presented in this paper. The multipath interference effects, that have typically been assumed negligible or approximated as Gaussian noise, become significant for low processing gain systems. In this paper, a scheme to accurately evaluate the multipath interference effects is proposed
