In the digital imaging equipment, Gaussian white noise and salt & pepper noise are both common noise source. 在数字成像设备中,高斯白(GW)噪声和椒盐噪声是两种常见的噪声源,对图像质量均有较大的影响。
Randomness in this case is modelled as a Gaussian white noise process. 模式中之随机性乃视为一高斯白(GW)噪音过程。
The channel to he measured is modeled as equivalent baseband Linear-Time-Variant channel with additive Gaussian white noise. 利用叠加高斯白(GW)噪声的线性时变等效基带信道模型来描述信道;
The paper is dedicated to study the influence of the additive Gaussian White(GW) Noise on the Spectral Correlation Density ( SCD ) analysis of Amplitude Modulated ( AM ) signals. 重点研究了加性高斯白(GW)噪声对调幅信号谱相关密度分析结果的影响。
The effect of bandwidth division on the improvement of the frequency spectrum utilization is analyzed under the condition of the multi-access interference and Gaussian white noise. 分析了在信道存在加性白噪声和多址干扰的条件下,频带细化对提高频谱利用率的作用。
