摘要:

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.

Abstract:

Measurements and characterizations are rarely conducted about indoor self-interference channel of CCFD(Co-time Co-frequency full-duplex).An extensive self-interference channel measurement is performed at 2.6GHz under typical indoor environment with channel sounder based on vector network analyzer.By analyzing the measurement data,the empirical channel characteristics such as path loss exponent,RMS(root-mean-square)delay spread have been extracted.Results show that path loss exponent and RMS delay statistics are different according to antenna separation of transmitter-receiver.When the separation is larger than 1m,the path loss exponent is 1.86,and the RMS delay statistics follow lognormal distribution.When the separation is less than 1m,the path loss exponent is 1.52,and the RMS delay statistics at different antenna separation follow lognormal distribution whose mean and variance are linear functions of antenna distance respectively.

Key words: 2.6GHz, channel measurement, indoor channel modeling, self-interference channel
