Abstract :
In this paper, some results of an extensive simulation study concerning the efficiency of turbo coding in downlink WCDMA receivers using two type of chip level equalizers - one common pilot channel-trained, the other prefilter-RAKE - are presented. Their performances are compared to the performances of the conventional RAKE receiver under various scenarios. Special consideration is given to the number of iterations needed for an efficient turbo decoding.
