transmitted spectrum

基本解釋

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.
本文就實際工程中遇到的信號頻譜惡化問題提出了解決的方案，達(dá)到改善發(fā)射信號頻譜的目的，并用實際的測試結(jié)果進(jìn)行了驗證。
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)不僅能對傳輸信號進(jìn)行頻譜成形來提高系統(tǒng)的頻帶利用率，而且還可以減小信號的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，無人機(jī)數(shù)據(jù)鏈系統(tǒng)采用的調(diào)制模式都比較簡單，如2FSK、BPSK、直接擴(kuò)頻技術(shù)等，傳輸速率與抗干擾能力有限。
