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.
對於MPSK信號而言，信噪比的估計可以直接轉(zhuǎn)化成對信號模的估計問題。
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的信噪比，減弱檢測噪聲對於缺陷散射特征的影響，從而突出缺陷特征信息。
