signal-to noise ratio snr

基本解释

For MPSK signals, the signal-to-noise ratio (SNR) estimation can be directly transformed into the signal module estimation.
对于MPSK信号而言，信噪比的估计可以直接转化成对信号模的估计问题。
In deep space communications, one of the problems is how to transmit message credibly in low signal-to-noise ratio(SNR)channel environment.
深空通信中面临的问题之一就是如何在低信噪比信道环境下可靠地传递信息。
A method for reducing noise based on high-order spectra was presented by which the signal-to-noise ratio(SNR) could be improved significantly and the flaw characteristic information could stand out.
提出了基于高阶谱的减噪方法，能有效提高回波信号的信噪比，减弱检测噪声对于缺陷散射特征的影响，从而突出缺陷特征信息。

Studio-grade components, which include external digital-to-analog converters (DACs) that deliver 127dB signal-to-noise ratio (SNR), sockets for swappable Op-Amps, a high-end 80mW into 600 ohm headphone amplifier, and 192kHz pass through, are used to deliver phenomenal audio quality.
