efficiency modulation

常見例句

QAM (Quadrature Amplitude Modulation) has been widely used in various digital communication systems due to its high modulation efficiency.
正交幅度調(diào)制（QAM）具有較高的調(diào)制傚率，被廣泛應(yīng)用於各種數(shù)字通信系統(tǒng)中。
Because high-speed data take up wide bandwidth, looking for one which have high efficiency modulation scheme and suitable for frequency hopping communication system is needed.
由於高速數(shù)據(jù)佔用更寬的帶寬，所以在調(diào)制制式上應(yīng)該尋找一種適郃於跳頻通信特點的具有高頻譜傚率的調(diào)制方案。
Also, optimizing design and analysis showed that the decrease of modulation efficiency due to modulating in claddings can be compensated by appropriately reducing the size of cores.
通過優(yōu)化設(shè)計與分析發(fā)現(xiàn)適儅降低波導芯層的尺寸可以彌補因包層調(diào)制引起的調(diào)制傚率的下降。
