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的力量都具有重要意义。 该代码针对10...
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
W = sqrt(variance).*randn(1,size(Xmodt,2)); %Gaussian white noise W Xmodt = Xmodt + W; %Add the noise I know that in this example variance equals to 1, but I need to find a general solution. So, is this code correct? Thanks in advance!0 Comments Sign in to c...

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: ...
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'); ...
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...
MATLAB Online에서 열기 You can generate normally-distributed random values with randn. For a point cloud for example, if you have 100 points with x, y, z values, you can create a noise array to add to the point array: >> gaussNoise=randn(100,3); ...
