carrier to noise ratio

释义

carrier to noise ratio

简明释义

载噪比：在电信中，载噪比（常写作CNR或C/N）是调制信号的信噪比（SNR）。该术语用于区分射频通带信号的CNR和解调后的模拟基带消息信号的SNR。例如，在FM广播中，100 MHz载波的强度与调制一起被视为CNR，而音频频率的模拟消息信号则是SNR；在每种情况下，与明显的噪声相比。如果不需要这种区分，通常使用SNR代替CNR，具有相同的定义。

双语例句

1
From signal to noise ratio analysis of the modulation signal, we choose the phase modulation method as the suitable carrier modulation for the twisted-pair.
本章首先分析了各种数字载波调制方法，从调制信号信噪比的角度分析说明基于相位调制的方法适合作为双绞线载波调制的方法。
2
As a result, it would carse more serious noiSe and distortion, In order to improve the reception quality, we are asked to make better design of a carrier for its noise ratio and CTB target.
为了提高收视质量，对系统设计中的载噪比和复合三次差拍（CTB）指标必然提出更高的要求。
3
But to the CW pulse signal with changing carrier wave frequency, common filter cannot achieve narrowband filter, whereas broadband filter cannot reach the request of the signal-noise ratio.
可是，对于载波频率不断变化的CW脉冲信号，普通的滤波器难以实现窄带跟踪滤波，而宽带滤波又不能达到提高信噪比的要求。
