Abstract

Abstract: In the CDMA system, the inter-path interference (IPI) becomes very serious when the spreading factor is low. In order to decrease IPI, a low complexity receiver structure in the low spreading factor for the CDMA system which combines the conventional Rake with chip equalizer is proposed. Computer simulation shows that the Equalizer-Rake receiver performs better than Rake and chip equalizer with equal complexity.

Key words: Equalizer-Rake receiver, inter-path interference (IPI), low spreading factor
