本文阐述了相干“DAR”隐分集机理,导出了相干“DAR”隐分集增益的工程近似表达式,指出了在工程实际上几种较实用的信道信号波形的隐分集增益的理论极限。文章最后给出了相干“DAR”隐分集增益的模拟信道实验结果。
In this paper, the coherent “DAR” implicit separable mechanism is expounded and the engineering approximate expression of coherent “DAR” implicit diversity gain is derived. The theoretical limits of implicit diversity gain of several practical channel signal waveforms are pointed out. At the end of the article, we give the experimental results of analog channels with coherent “DAR” implicit diversity gain.
