摘要
"跨山通信"是通信领域研究的一个热门话题,越来越受到各国的重视。首先对2条实测链路的数据进行了分析,得到了对流层散射近距离跨山信道的损耗特性与快衰落特性;然后用matlab计算了2条典型跨山通信链路的传输损号,理论计算与实测结果误差相差在3dB以内;最后仿真了散射近距离跨山的信道模型,通过对仿真结果的分析和对比,验证了该模型建立的正确性。
Communication across mountains is a hot topic in communication,more and more countries pay great attention to it.Firstly,the data of two real measured links are analyzed,the characteristics of loss and fast fading about troposcatter channel across mountains are obtained.Then,the transmission loss of two real troposcatter communication links across mountains is calculated by MATLAB,the error between theoretical and experimental results is less than 3dB.Finally,the simulation about the model of troposcatter channel across mountains is obtained,the analysis and comparison of simulation results show that the model is valid.
