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.
正交幅度調制（QAM）具有較高的調制效率，被廣泛應用于各種數(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.
由于高速數(shù)據(jù)占用更寬的帶寬，所以在調制制式上應該尋找一種適合于跳頻通信特點的具有高頻譜效率的調制方案。
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)化設計與分析發(fā)現(xiàn)適當降低波導芯層的尺寸可以彌補因包層調制引起的調制效率的下降。
