Abstract:

目前,对同时同频全双工的自干扰信道特性尚未进行研究.针对这一现状,采用基于网络分析仪的信道测量平台,对室内环境下2.6GHz同时同频全双工自干扰信道特性进行测量与分析.基于实测数据统计分析,得出了传输损耗模型与均方根时延扩展统计模型.结果表明:传输损耗服从断点损耗模型,天线间距在大于1m的传输损耗指数为1.86,天线间距小于1m的传输损耗指数为1.52;均方根时延扩展的统计特性随着天线间距在不同范围而不同,在天线间距大于1m时的均方时延扩展服从lognormal分布,在天线间距小于1m时,RMS时延扩展在不同的天线间距下服从lognormal分布,并且其分布的均值与标准差与天线间距呈现线性关系.
