摘要

本文介绍了基于统计Saleh-Valenzuela模型的通道仿真方法在典型大学建筑结构中的应用。参数的估计是基于对同一建筑物内测量活动中测量到的功率延迟曲线的分析。在1600 ~ 2000mhz频段内采用矢量网络分析仪进行测量。所有的测量都是在单层楼上进行的。根据实测的空间平均功率延迟曲线，对簇到达率、射线到达率、簇衰减因子和射线衰减因子进行了初步评估。为了优化信道参数，将模拟的有效时延累积分布函数与实测的进行了比较。最后的结果是模拟的CDFs和测量的CDFs非常吻合

Estimation of Channel Parameters for " Saleh-Valenzuela" Model Simulation

The paper presents application of channel simulation according to statistical Saleh-Valenzuela model for a typical university building architecture. Estimation of parameters is based on analyze of measured power delay profiles, obtained in measuring campaign inside the same building. The vector network analyzer method of measuring was applied, inside 1600 - 2000 MHz frequency band. All measurements were done on single-floor. The first assessment of cluster arrival rate, ray arrival rate, cluster decaying factor and ray decaying factor was gained from spatial-averaged measured power delay profiles. The simulated cumulative distribution function of effective time delay was compared with measured one in order to optimize mentioned channel parameters. The final result is a great deal of agreement between the simulated and measured CDFs
