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.
現有的點對點通信方式受頻譜資源和信道衰落等的限制已經無法滿足需求。
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統計特性包括多逕衰落特性、多普勒功率譜和時延功率譜。
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.
正交頻分複用（OFDM）具有高頻譜利用率及抗多逕衰落的特性，但其存在峰均功率比（PAPR）較高的問題。
