一、前言经多次野外试验证明:分离多径技术在对流层散射信道中作为一种带内分集手段是有效的。从体制试验看来,至今工作可以认为告一段落。但是作为工程应用则仍有一些问题尚待解决。例如:文献[1]证明,要想使得分离多径技术的实际效果接近其潜在工程效果,则其等效复制品数量要取十个左右,这时实用分离通道数量约在十五条左右。可见,就这种技术工
I. INTRODUCTION After many field experiments, it has been proved that ramification is effective as an in-band diversity method in troposcatter channels. From the perspective of institutional tests, the work so far can be considered as the end of the story. However, there are still some problems to be solved as engineering applications. For example, [1] proved that to make the actual effect of RK approach its potential engineering effect, the number of equivalent replicas should be about 10, and the number of practical separation channels is about 15 at this moment. Can be seen on this kind of technical workers
