摘要

在两波漫射功率(TWDP)衰落信道上，得到了最优和次优的无编码MQAM(多层正交调幅)自适应传输技术的频谱效率表达式。用信噪比的概率密度函数得到了表达式。研究了衰落参数对不同技术频谱效率的影响。

Power and rate adaptation techniques with uncoded MQAM over TWDP fading channels

Expressions of spectral efficiency have been obtained for optimal and suboptimal adaptive transmission techniques with uncoded MQAM (multilevel quadrature amplitude modulation) over Two Wave Diffuse Power (TWDP) fading channels. Probability density function of signal-to-noise ratio is used to obtain the expressions. A study of the effect of fading parameters on the spectral efficiency of different techniques has been presented.
