| 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. |

| Keywords: | inter-path interference (IPI) low spreading factor Equalizer-Rake receiver |
