基本解釋輻射頻譜英漢例句雙語(yǔ)例句This paper proposes a scheme to improve the quality of frequency spectrum of transmitted signals, and also validates the method by the actual test result.本文就實(shí)際工程中遇到的信號(hào)頻譜惡化問(wèn)題提出了解決的方案,達(dá)到改善發(fā)射信號(hào)頻譜的目的,并用實(shí)際的測(cè)試結(jié)果進(jìn)行了驗(yàn)證。Thus pulse shaping technique can be used not only shape the spectrum of the transmitted signal to increase the bandwidth efficiency but also to reduce its PAPR.因此脈沖成形技術(shù)不僅能對(duì)傳輸信號(hào)進(jìn)行頻譜成形來(lái)提高系統(tǒng)的頻帶利用率,而且還可以減小信號(hào)的PAPR值。The modulation types of data link for UAV are simple, such as BPSK, 2FSK , direct spread spectrum. The transmitted rate and anti-interference performance of them are limited.目前,無(wú)人機(jī)數(shù)據(jù)鏈系統(tǒng)采用的調(diào)制模式都比較簡(jiǎn)單,如2FSK、BPSK、直接擴(kuò)頻技術(shù)等,傳輸速率與抗干擾能力有限。transmitted spectrum更多例句詞組短語(yǔ)短語(yǔ)differential transmitted signal spectrum 差分傳輸信號(hào)頻譜transmitted spectrum更多詞組專業(yè)釋義物理學(xué)透射率光譜交通運(yùn)輸工程發(fā)射頻譜
