这项工作的目的是提高无线电信道特性在宏蜂窝场景。努力已经放在宽带和MIMO方面。测量已在两个室外和三个室内位置在5.25 GHz的带宽为200 MHz，使用矢量网络分析仪。使用光纤实现发射器和接收器之间的距离高达300米。信道参数的估计采用最大似然估计，信道模型采用一组离散的平面波。根据估计的联合双向，延迟和极化分布确定。此外，聚类和路径振幅的统计分布进行了研究。
The purpose of this work is to improve the radio channel characterization in macrocellular scenarios. The effort has been put on the wideband and MIMO aspects. Measurements have been performed at two outdoor and three indoor locations at 5.25 GHz with bandwidth of 200 MHz using a vector network analyzer. An optical fiber was used to achieve distances between transmitter and receiver up to 300m. The channel parameters were estimated by means of maximum likelihood estimation, modeling the channel with a set of discrete plane waves. Based on the estimates joint double directional, delay and polarimetric distributions were determined. Moreover, clustering and statistical distribution of path amplitudes were studied.
