光载波 meaning in English
light carrier
Examples
- Oc - n : optical carrier level - n
光载波级 - Indispensable for high quality optical carrier signal reception in a large dynamic range , agc analog optical receivers are widely used in the optical transmission of radio and microwave signals , such as fiber catv , direct broadcast satellite tv , wireless communication and radar
摘要自动增益控制模拟光接收机广泛应用于光纤有线电视、光纤直播卫星电视、无线通讯及雷达等射频微波信号光传输，是实现大动态范围光载波信号高质量接收必不可少的一项技术。 - Calculations indicate that the carrier phase takes effect till the time width of the pulse envelope becomes smaller than the period of the carrier oscillation , and the interpretation of this phenomenon is also presented . it is the difference between phase delay and group delay that causes the sliding between the carrier and the envelope
数值分析的结果表明，当脉宽小于光波周期时，相位的作用开始显现出来，当脉宽比光波周期长时，载波相位的作用可以忽略，并分析了相位起作用的原因，用解析的方法说明正是相延迟和群延迟之间的差别造成了光载波在脉冲包络下的滑动。 - A special address codeword produced by optical encoder at the side of transmission and data information are modulated on optical carrier and transferred . the data from different users are transmitted through optical fiber . the information belonging to local user is demodulated by the special optical decoder while optical signals carrying other users ’ information are filtered as noise
在发送端特定的光编码器产生某一特定的地址码,将数据信息与此地址码调制在光载波之上发送出去,不同用户的数据都在光纤媒质中传输,接收端用特定的光解码器解出属于自己的信息,而携带其他用户信息的光信号,就像噪声一样被过滤掉。
