rayleigh
- 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
OFDM
- 基于自适应压扩法降低OFDM系统的峰均比。正交频分复用(OFDM,Orthogonal Frequency Division Multiplexing)技术可以出色的对抗抗多径衰落、消除码间干扰且具有极高的频谱利用率。此外它还采用了快速傅立叶变换,大大降低了收发机的实现复杂度,因此被广泛地应用于HDSL、ADSL、DAB、HDTV、WLAN等领域中。 但是,目前OFDM技术还有很多关键问题没有得到有效解决,如对频偏敏感、高峰均功率比问题等,这些都限制了OFDM技术的近一步广泛应用。本论文主要
