The invention discloses a channel modeling method and parameter matching method based on non-uniform scatterer distribution, which belongs to the technical field of wireless communication. The invention based on the improved channel model realizes and introduces two physical concepts such as a scattering probability and a effective scatterer, comprehensively describes a propagation characteristic in various specific environments accurately and flexibly, conveniently estimates a mobile communication environment of a macro cell, a microcell and the like accurately and flexibly, and effectively improves accuracy of an electromagnetic signal wave arrival angle, a wave arrival time, a Doppler effect and other channel parameter. The invention based on the established channel model, according to a channel information of receiving end, according to the channel state reasonably distributes an antenna and power resource, thereby effectively reaching the maximum vaue of the channel in the condition of no-increase channel bandwidth, and improving the resource utilization efficiency of the channel.
