The analyses of channel characteristics in spatial vector channel

Spatial vector channel is an important part of smart antenna system that has attracted wide interest in the world. However, some important characteristics of the spatial vector channel, such as joint pdf of DOA and TOA, power delay spectrum and power angle spectrum, have not clearly been studied. In this paper, we first give the theoretical analyses of these problems based on the simple geometrical position relation of the base station, mobile station and scatterers, then the characteristics of a specific spatial vector channel model in which the scatterers are uniformly distributed in a ring scatter area are discussed in detail. The similarity of the simulation and theoretical results prove the correctness of the theoretical analyses of spatial vector channel.
