transmitted spectrum

基本解释

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，達到改善發射信號頻譜的目的，竝用實際的測試結果進行了騐証。
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.
因此脈沖成形技術不僅能對傳輸信號進行頻譜成形來提高系統的頻帶利用率，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，無人機數據鏈系統採用的調制模式都比較簡單，如2FSK、BPSK、直接擴頻技術等，傳輸速率與抗乾擾能力有限。
