Performance analysis of pilot signal aided coherent RAKE receiver in IMT-2000 system

Firstly, the paper describes two channel estimating ways adopted in downlink and uplink channels of IMT-2000 systems: pilot channel and pilot symbol group. Then the simulation models of the RAKE receiver's phase estimation and the model of the multipath fading channel of ITU-R M.1225 are established. Finally the simulation results are given and analyzed.
