摘　　要：为提高对空时到达分布预测的准确度,介绍了一种适用于宏小区高天线环境下波达角度和时间预测、的改进的圆散射模型。分别给出了波达角度和时间分布概率密度函数的表达式。仿真结果与实测数据的比较表明,较传统的基于散射体的单反宏小区模型而言,改进的圆模型能更合理地对传播建模,且在波达角度和时间的预测方面具有更高的准确度。In order to improve the modeling accuracy of spatial-temporal arrival distribution, an enhanced circular scattering model （ECSM） for predicting the azimuth of arrival （AOA） and the time of arrival （TOA） in macrocell with high base station antenna is presented. Expressions for the probability density functions of AOA and TOA are deduced, respectively. The comparison of simulated results with measured results shows that, the ECSM can model the propagation more reasonably and has obvious higher accuracy than the geometrical based single bounce macrocell channel model in both AOA and TOA prediction.
