摘　　要：研究了在典型城市室外环境下的3·5GHz无线信道的小尺度传播特性,构建了一个用于信道测量的测量系统,完成了固定与移动场景下的信道测量,得出了功率延迟分布(PDP)、抽头延迟线模型、多径分布和莱斯K因子等参数,测量结果证明该环境提供了多天线无线通信所需要的富散射环境.The small-scale multipath propagation characteristics of the wireless channel at 3. 5 GHz was studied in a typical outdoor urban environment. A channel measurement platform was developed for the measurement. Both the fixed and mobile scenarios were measured; the power delay profile （PDP）, the tapped delay line model, the multipath distribution, the mean excess delay and the Ricean K-factor were presented. The results verify that it is a rich scattered environment fit for multiple antenna wireless communications.
