carrier-to-noise ratio c/n
cnr carrier-to-noise ratio
Examples
- Carrier - to - noise ratio
载波噪声比,载噪比 - This dissertation focuses on the carrier recovery in high dynamic navigation receiver , the effect of iq mismatch in direct down conversion receiver and the signal to noise ratio estimator in navigation receiver
本文以二代卫星导航定位系统为应用背景,着重研究了接收机中的载波恢复技术、 iq非正交对伪码和载波影响的模型、载噪比估计技术。 - This instrument can meter the electric level , frequency spectrum , carry to noise ratio , a / v , cobbly ratio , voltages of the ac trunk line and the battery . furthermore it can display the above information on the lcd and store them in the eprom
该场强仪可以对有线电视系统的电平、频谱、载噪比、 a v比、系统不平度、交流干线和电池电压等进行测量，并通过液晶显示，结果保存于eprom中。 - In order to monitor the satellite , carrier to noise ratio estimator is needed in receiver . the widely used carrier to noise ratio estimator is sensitive to residual doppler frequency . we present a new estimator whose property is somewhat better than the widely used one
以上的研究均以实际应用需求为出发点,充分考虑了实际实现中的可能会遇到的问题,其中载噪比估计及载波跟踪技术已成功地应用到某国防重点型号的接收机中。 - In this thesis , a qpsk channel monitoring solution is applied . by monitoring the parameters of carrier power , c / n rate and noise of the channels , analyzing their changes , and judging by these parameters , alarms of interferences of illegal signals are implemented
本课题中采用qpsk信道监测方案,通过监测信道中的信号状态参数:载波功率( power ) 、载噪比( c / n )和噪声( noise ) ,分析它们的变化情况,并进行综合判决,最终实现对非法信号干扰的报警提示。
