摘要 协作通分集的主要思想是通过多用户系统中的各个用户之间的独立天线合作传输信息,产生虚拟的MIMO系统。协作通信在无线网络中的应用大大改善了系统性能,文中从网络结构的角度,分析不同层对协作通信的影响,并提出了一个跨层的网络设计模块,通过优化网络设计提高系统性能。 The cooperative diversity enables single-antenna mobiles in a multi-user system to share their antennas so that each mobile is served by a virtual multiple-antennas transmitter or receiver. In this paper, radio resource management is introduced and the method of cross-layer design implemented in cooperative diversity is analyzed.
