uwl多径衰落信道的分集技术当信道于深度衰落时(信道对传输于其中的信号衰减比较大时)，接收端的判决信息会出现错误，分集技术就是为了减小此类错误的发生。分集技术的思想是提供给接收机同一信号经过几个独立路径到达的几个信号。-uwl multipath fading channel sub-set of technical

服从频率选择性衰落并且也服从瑞利衰落的信道。-Subject to frequency selective fading and also subject to Rayleigh fading channel.

瑞利信道模型建模平坦衰落等，并且加入赖斯信道模型进行改进。模拟了信道的小尺度衰落问题，和Clarke模型进行比对-Rayleigh flat fading channel model, and joined the Rice channel model is improved. Simulation of small scale fading channel, and the Clarke model are compared
