random noise background

基本解释

Self adaptive predictor is used to extract periodic signals with unknown frequencies from wide band random noise background.
自适应预估器能用来提取宽带随机噪声背景中未知频率的周期性信号。
This will prevent the software from accepting hot pixels random background noise peaks or cosmic ray strikes as real objects.
这个设置将对软件排除热噪点、背景噪声尖峰以及宇宙射线有用。
By means of the principle of correlation analysis, this paper introduces an approximate method for estimating signal-to-noise ratio on random noise background.
本文利用相关分析的原理，提出一种在随机噪音的背景上估算信噪比的近似方法。
