中文摘要：

针对指向性天线所造成的覆盖区域面积是非对称特点，建立了非对称空间分布的空间统计信道模型，并且提出两种情况，一种是移动接收台（MS，MobileStation）在覆盖区域内，另一种是移动接收台MS不在覆盖区域内。利用统计分析的方法，通过推导计算出在此空间统计信道模型下的到达时间（TOA，TimeofArtival）概率分布密度函数。实验仿真结果表明本模型的信道参数估计结果符合理论和经验，拓展了空间统计信道模型的研究和应用。

英文摘要：

A geometrically-distributed statistical channel model in cellular mobile system is proposed. TOA （time-of-arrival） distribution is derived in a closed-form explicit formula between omni-directional transceiver and directional transceiver. This channel model assumes that each multi-path component of the propagating signal undergoes only one bounce traveling from the transmitter to the receiver. The omni-directional transceiver is located in the limited beamwidth, even the omni-directional transceiver is lying altogether outside the directional beamwidth.
