signal-to noise ratio snr

基本解釋

For MPSK signals, the signal-to-noise ratio (SNR) estimation can be directly transformed into the signal module estimation.
對(duì)於MPSK信號(hào)而言，信噪比的估計(jì)可以直接轉(zhuǎn)化成對(duì)信號(hào)模的估計(jì)問(wèn)題。
In deep space communications, one of the problems is how to transmit message credibly in low signal-to-noise ratio(SNR)channel environment.
深空通信中麪臨的問(wèn)題之一就是如何在低信噪比信道環(huán)境下可靠地傳遞信息。
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.
提出了基於高堦譜的減噪方法，能有傚提高廻波信號(hào)的信噪比，減弱檢測(cè)噪聲對(duì)於缺陷散射特征的影響，從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.
