Rapid fading and so on. then we introduce the qam schemes of modulation about the design of parameters and constellations of qam and show the result of 8qam and 16qam. afterward we switch to the study of adaptive project, above all, we find that we can alter the parameter of nakagami fading channels to other fadings, and then we study three different adaptive projects
首先，闡述了移動通信中通道的衰落特性，分別分析通道的陰影衰落、慢衰落、快衰落幾種模型；接著對qam的調制原理進行了分析，著重研究了這種調制方式的參數設置以及星座圖的設計，文中示出了8qam和16qam的框圖和波形情況。 -
With rapid development of wireless communications, muitipath radio channel simulation has become an indispensable means of evaluating radio links. transmission of information over muitipath fading radio channel, such as the land - mobile hf or vhp channel has received much attention during the last three decades
