摘要

为提高电磁信号的到达角度以及多普勒效应等信道参数估计的准确性，在散射体非均匀分布下引入了散射概率和有效散射体两个物理概念，提出一种合理的改进型空间信道模型，该模型能准确地描述宏小区（macrocell）和微小区（microcell）等各种移动通信环境下的重要空时信道参数，并应用于多入多出系统（multiple input multiple output，MIMO）信道性能仿真中. 数值仿真结果与早期多径衰落信道模型对比，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，对评估多天线MIMO 系统空时处理算法和仿真无线通信系统提供有力的工具.

Abstract

For testing an adaptive array algorithm in cellular communications, we develop a geometry based statistical channel model that provides the statistics of angle-of-arrival and doppler spectra of the multi-path components, into which introduced are the new concepts of effective scatterers and reflection probability. This channel model is suitable for describing the outdoor and indoor propagation environments, which is applied to the performance of multiple input multiple output (MIMO) system. A comparison between our theoretical calculations and customary results shows that the analysis is correct and applicable to microcell environments, which can promote the research of the statistical channel models and provide accurate and flexible channel models for the MIMO multi-antenna systems.
