Simulation results show that the algorithm is effective to reduce the impacts of impulse noise , white gaussian noise and gaussian colored noise 仿真实验结果表明:该算法对于冲击噪声有抑制作用,对高斯白噪声、高斯有色噪声也有一定的抑制效果。
The white gaussian noise was successfully separated from noise signal in low - field pulse nmr system and its parameters were estimated by using this method 采用该方法从实际低场脉冲核磁共振系统噪声信号中分离出高斯白噪声并对其进行了参数估计。
So the signal generated by iteration of simple chaos mathematical model get the feature of randomness and owns the statistical characteristics similar to white noise 因此,利用简单混沌数学模型迭代产生的信号具有随机性,其统计特性类似白噪声。
Our experiments show that this method is also robust to gaussian white noise . resampling and smoothing etc . . at last , some discussions and conclusions are given 实验结果显示,我们的算法在高斯白噪声、重采样、运动光滑等攻击下有很好的鲁棒性。
This approach only requires the noise inputs to be energy - bounded instead of gauss white noises . the main results can be expressed by lmi after some matrix manipulations 该方法不需要限定系统的噪声输入信号为高斯白噪声,而只要求噪声信号为能量有界。
Experimental results demonstrate that the algorithms are robust and imperceptive at the attack of noise stain , low - pass filtering and sampling again 仿真实验表明,本课题提出的各种算法能有效地抵抗白噪声污染、色噪声污染、低通滤波和重采样对水印的攻击。
If one wants to retrive the encryping datable or she must know the phase keys and wavelength keys simultaniously , otherwise , the reconstructed data will be white noise like 要想得到存储信息必须同时知道相位匙和波长匙,否则得到的数据将是一白噪声系列。
In the system of the online measuring of pellets diameters , the disturbed noises during the process of collecting pellets images are mainly impulse noise and white noise 摘要在球团矿粒度在线检测系统中,球团图像采集过程的干扰噪声主要是脉冲噪声和白噪声。
The sequences based on chaotic system get the traits of white noise can be the pn code of cdma system . many papers proved its feasibility 基于混沌的伪随机序列具有类似白噪声的统计特性,完全可以取代传统序列作为cdma通信系统的pn码,已有大量文章证实其可行性。
In chapter 3 , under the wideband radar system , some parameter estimation methods of scattering center are studied in the white noise and clutter background 第三章以宽带阶梯变频雷达为研究背景,在白噪声和杂波条件下,研究了提取目标强散射中心的参数估计方法。
