由于信号进行多径传播达到接收点处的场强来自不同传播的路径，各条路径延时时间是不同的，而各个方向分量波的叠加，又产生了驻波场强，从而形成信号快衰落称为瑞利衰落。-Because the signal carries on the multipath propagation to achieve the point of reception place field intensity from the different dissemination way, each way delay time

协作分集：提出了一个能抵抗无线网络多径衰落的协作分集协议-low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks
