信道间 meaning in English
interchannel
Examples
- Single pole double throw switch ( spdt ) mainly complete the conversion of the signal between difference channels , the control element in common use is pin diode and gaas mesfet
单刀双掷开关( spdt )主要用来完成信号在不同信道间的转换，其常用的控制器件有pin管和gaasmesfet两种。 - In such dense wavelength division multiplexing ( dwdm ) systems a light source having narrower linewidth and further stability of the wavelength has become a requirement
在这样的密集波分复用( dwdm )系统中，光发送机的工作波长必须稳定，线宽必须窄，以避免复用信道间信号相互窜扰。 - A group of orthogonal frequency carriers are used in ofdm system to improve the using rate of spectrum . if the orthogonal character can be held and ignore the inter - channel interference ( ici ) , the symbol error character of ofdm depend on the modulate of source codes . this dissertation propose the theoretic formula of ofdm - qam and ofdm - psk in this precondition
为了提高频谱利用率, ofdm系统使用了一组正交的子载波来传输信号,若能保证各子载波间的正交性不被破坏、不考虑信道间干扰( ici ) ,则ofdm系统的误码性能由信元调制方案的误码性能决定,文中推导了该情况下ofdm - qam和ofdm - psk的理论误码率公式。 - In wavelength division multiplexing ( wdm ) optical communication networks , power equalization and adjustment between channels demand variable optical attenuator ( voa ) be capable of providing low power consumption , low insertion loss , polarization independence , integration compatibility and flatness in a wide wavelength range . among the presented voas , thermo - optic type owns superior polarization dependence upon electro - optic one , and thermo - optic voa can be driven with much lower power than micro - electro - mechanic system ( mems )
在波分复用( wdm )光通信网络中，多信道间的功率均衡和调整需要具有良好特性的光可变衰减器( voa ) ，这些特性包括：低功耗、低插入损耗、偏振无关、易于集成以及大波长范围内的通带平坦性。
