GBSBEM(几何单反射椭圆模型)可以用来仿真功率－延迟－角度（pda-图）、功率延迟图、时间－角度的联合统计、波达方向的边缘特征和窄带衰落包络。适用于低层系统，包括微小区和微微小区、杂波绕射基站天线、发射机到接收机之间以及发射机和接收机的周围充斥着散射体的情形。由于其适用范围广泛且具有解析性质，揭示了空间无线信道不同特征间的相互联系，是进行研究的理想模型。-GBSBEM (geometric GBSBEM) simulation can be used to power-delay-angle (pda- Chart), power plans delayed, time-point joint statistics, DOA on the brink of decline and narrow envelope. Apply to the lower systems, including Microcell and Microcells, Clutter diffraction base station antenna, between the transmitter and receiver to the transmitter and receiver around the full scattering case. Because of its broad scope of application and analytic nature, Space Channel reveals the different features of the inter-linkages Research is the ideal model.
