Abstract :
In this paper the interleaving gain, due to the channel interleavers, corresponding to BER (bit error rate) and FER (frame error rate) in an advanced 3G (WCDMA) receiver, using chip level equalizer and turbo coding, is analyzed by simulation. The waterfall region is considered. The conventional RAKE receiver is used as a reference. MAI (multiple access interference), usually modelled as an additive white Gaussian noise, is simulated by generating signals of other users strictly according to the standards. The simulation results for both receivers (RAKE and advanced one) show that channel interleaves enhance performance considerably.
