Abstract: In order to effectively weaken the multipath effect and improve the accuracy of channel parameter estination in wireless communication,a new channel model which is more adapted to different cell types was presented and a new concept of range of arrival was introduced,under the condition of the non-uniform distribution of the scatterer.This model can describe the important parameters in marcocell environments precisely,such as angle of arrival and range of arrival at the base station.In addition, the received signals of the base station has Doppler shift effect due to the mobility feature of mobile station,and the probability distribution of Doppler shift is derived.The numerical simulation results of the model compared with multipath fading channel models in other literatures show that channel parameter estimation results of the model accord with the theory and experience,which expands the research and application of statistical channel model and provides powerful tools for the simulation of wireless communication system.
