摘　　要：基于典型的室内走廊环境,对60GHz毫米波通信信道参数及其相关特性进行了研究.在视距和非视距条件下,分析了信道参数包括多径个数、均方根时延扩展、莱斯因子、阴影衰落的特点及其分布模型,研究了信道参数之间的相关特性.结果表明:在视距条件下各参数之间普遍具有较强的相关性,而在非视距条件下只有均方根时延扩展和多径个数之间的相关性较强.利用信道参数的相关特性可从一个参数来预测另一参数,为60GHz无线通信系统的设计提供有用信息.In this work,indoor channel parameters and correlation properties are studied based on experimental measurements performed at 60 GHz in typical corridors for both line-of-sight(LOS)and non-line-of-sight(NLOS)scenarios.Specifically,channel parameters like number of paths,root mean square(RMS)delay spread,Rician K-factor,and shadow fading are extracted from measurement data,and parameter distributions are analyzed further.Channel parameter correlation properties are also studied.Results show that in the LOS corridor channel parameters are highly correlated,in the NLOS corridor only RMS delay spread and number of paths are correlated highly.The excellent correlation property can provide useful information in predicting channel parameters from one another for design of 60 GHz wireless communications systems.
