英文缩写词PRE-MOD的例句
- 40 Gb / s simulation and 10 Gb / s experiment are performed using tunable clock or data-related signal as the phase pre-modulating signal. The eye opening and receiver sensitivity are improved and the dispersion tolerance is doubled when the phase pre-modulation is imposed on NRZ signals.
- 10Gb/s实验和40Gb/s仿真结果表明,采用时钟信号和数据相关信号对非归零码进行可调节的相位预调制(PRE-MOD),可增加信号的眼图开启度和接收灵敏度,将系统的色散容限提高1倍左右。
- The main points are as follows : 1. A new method to improve dispersion tolerance by imposing phase pre-modulation on non-return-to-zero ( NRZ ) format is put forward in this dissertation.
- 取得以下主要研究成果:1、提出了一种对非归零码进行相位预调制(PRE-MOD),提高系统色散容限的方法。
- This scheme relaxes the requirement of optical signal-to-noise ratio and dispersion management. It also benefits the NRZ system upgrade because the phase pre-modulation is easy to be employed and adjusted at the transmitter. 2.
- 该方法降低了系统对光信噪比和色散管理的要求,且由于相位预调制(PRE-MOD)在发射端进行,调节方便,实施简单,便于系统升级。
- The bit-synchronous phase pre-modulation imposed on non-return-to-zero ( NRZ ) signals at the transmitter can reshape the NRZ pulse to return-to-zero ( RZ ) waveform and hence improve the eye opening.
- 通过在发射端对非归零(NRZ)的光信号进行比特同步相位预调制(PRE-MOD),使非归零码在传输过程中得到波形重整,演变为归零(RZ)的波形,从而提高眼图开启度。
