Abstract: Multi-carrier and direct spread are used in CDMA2000 for supporting wideband data service. To improve performance of the receiver, the pilot channel is added to the reverse channels. But the signals of I and Q are different now. In this paper, we introduce the structure of the reverse channels and discuss the principle of the Rake receiver. Basing on this, we set up the model of the Rake receiver and carry out computer simulations. Finally, we analyze the result and draw an ideal conclusion.

Key words: the third generation mobile communication, CDMA2000, Rake receivers, maximal ratio combining
