高斯求积代码matlab 高斯噪声 对加性高斯白噪声对脉冲幅度调制的影响进行建模,并对损坏后的位进行最佳检测,然后找出信噪比或误码率。 这是我的课程ICSI 660:高级通信工程的一部分。 使用MATLAB(类似于Python的语言)从头开始编写,完全是原创作品。 尽管不是很重要,但是最佳检测在许多领域中对于利用已应用的AI的力量都...
工具Matlab/simulink软件方法步骤打开Matlab/simulink（本人用的是Matlab2012a）在communications system toolbox下找到noise generators,选择gaussiannoisegenerator建立新simulink页面，将gaussiannoisegenerator拉入运行看下效果
本文科普一下高斯白噪声(white Gaussian noise,WGN)。 百度百科上解释为“高斯白噪声,幅度分布服从高斯分布,功率谱密度服从均匀分布”,听起来有些晦涩难懂,下面结合例子通俗而详细地介绍一下。 白噪声,如同白光一样,是所有颜色的光叠加而成,不同颜色的光本质区别是的它们的频率各不相同(如红色光波长长而频率低,相...

Open in MATLAB Online Hey, I have a signal Xmodt to which I want to add Gaussian white noise W with mean value equal to zero (by definition) and variance equal to 1/(Ts*(10^(SNRdb/10))). From what I have found online, I created the following code: ThemeCopy Ts=0...
MATLAB Online에서 열기 Hello community, I have the PSD of a noise from an IMU that is 10e-12 from this value of the PSD I wanted to create a gaussian noise of 1e6 samples. Now I want to compare this noise with the noise of an accelerometer that has the PSD like this: ...
MATLAB Online で開く To add white Gaussian noise: (assuming you are adding noise for each time step, have your signal in vector 'signal') rnoise=randn(1,NoTimeSteps); NoiseAddedData=signal+rnoise; something like this should work. (FYI, I'm modifying this from my code on Sensor network...
Open in MATLAB Online salt_and_pepper_noise_removal.m salt_and_pepper_noise_removal_grayscale.m For Gaussian noise, the maximum likelihood de-noised answer would just be a local mean, which you can do with conv2(): denoisedImage = conv2(double(noisyImage), ones(3)/9,'same'); ...
