由于多径和移动台运动等影响因素,使得移动信道对传输信号在时间、频率和角度上造成了色散,如时间色散、频率色散、角度色散等等,因此多径信道的特性对通信质量有着至关重要的影响,而多径信道的包络统计特性成为我们研究的焦点。根据不同无线环境,接收信号包络一般服从几种典型分布,如瑞利分布、莱斯分布和Nakagami-m分布。-Because multipath and mobile and other sports influence factor, makes mobile channel in tran

正交频分复用(OFDM)技术是一种可以有效对抗符号间干扰(ISI)的高速数据传输技术。OFDM是一种特殊的多载波调制方式,它的基本思想是将高速传输的数据流通过串/并转换,变成在若干个正交的窄带子信道上并行传输的低速数据流。OFDM接收机有三个关键技术:信道估计技术,降低峰均比(PAPR)技术和同步技术。OFDM技术能有效的对抗多径衰落等,有着诸多的优点,但是OFDM有一个发展瓶颈,即OFDM信号的峰均功率比很大,很容易导致OFDM信号的交调失真和系统性能的下降。因而如何降低OFDM信号的峰均功率
