本文研究了一种适用于微蜂窝环境的三维饼状蜂窝切割(PCC)散射信道模型,该模型将位于三维散射半球体内部的移动站(MS)和在半球体中心采用定向天线的基站(BS)理想化。推导了BS和MS的到达角(AOA)和到达时间(TOA)与方位角和仰角对应的联合概率密度函数(PDF)和边缘概率密度函数(PDF)。结果表明,与已有的室内和室外二维散射信道模型相比,本文提出的三维散射信道模型具有更好的性能,促进了统计信道模型的研究。
In this paper, investigated a 3-D pie-cellular-cut (PCC) scattering channel model for microcell environments, that idealizes the mobile station (MS) located inside of a 3-D scattering semispheroid and base station (BS) employing a directional antenna at the center of the semispheroid. The joint probability density functions (PDFs) and marginal PDFs of Angle of arrival (AOA) and Time of Arrival (TOA) seen at the BS and the MS in correspondence with azimuth and elevation angles are derived. The results show that the proposed 3D scattering channel model performs better compared with previously proposed 2D models for outdoor and indoor environments, which promotes the research of the statistical channel models.
