Abstract :
Firstly, the paper describes two channel estimation methods adopted in the downlink and uplink channels of WCDMA systems: pilot channel and pilot symbol group. Then, the simulation models of the RAKE receiver´s phase estimation are established and the multipath fading channel model of ITU-R M.1225. Finally, the simulation results are given and analyzed.
