fading spectrum

基本解释

The existing point to point communication methods limited by the spectrum of resources and fading channel has been unable to meet demand.
现有的点对点通信方式受频谱资源和信道衰落等的限制已经无法满足需求。
The statistic model of air-ground radio communication channel is characterized by the multipath fading, Doppler power spectrum and delay power spectrum.
空地通信信道的主要统计特性包括多径衰落特性、多普勒功率谱和时延功率谱。
Orthogonal Frequency Division Multiplexing(OFDM) can efficiently use of radio spectrum and withstand multipath fading, but the high level of Peak Average Power Ratio(PAPR) is a major drawback.
正交频分复用（OFDM）具有高频谱利用率及抗多径衰落的特性，但其存在峰均功率比（PAPR）较高的问题。
