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...

I want to generate correlated complex white Gaussian noise signals in MATLAB. What I do is that I take complex Gaussian random variables with unit-variance and multiply them with the desired input covariance matrix. Next I have to send this signal through a bandpass filter to get the desired ...
I want to create a 2D variable (Y1, Y2) whose probability density function is 1/sqrt(2*pi*sigma1*sigma2)*exp[(Y1-mu1)^2/2/sigma1^2]*exp[(Y2-mu2)^2/2/sigma2^2] Do you have any idea how to do it? I know gnoise can create 1D Gaussian noise, but it seems Igor does no...
One (inefficient) way is to just create more than you need and throw away any outside the range. Of course this might make it not purely Gaussian anymore What
aThe main design problem address in this paper is how to generate in the cheapest way, Gaussian noise signals with low cross-correlation values. There are two quite important characteristics that this generation technique should exhibit: 主要设计问题地址在本文是如何引起用最便宜的方式,高斯噪声信号以低...
I think it's not an easy task to sample a noise vector to generate an image, even with a well-trained autoencoder, since the well-learned latent space may not be an ideal gaussian space. Let's say, the training data set has its own distribution, P(x). After passing through the enc...
gaussian. You add noise signal to your signal sample by sample. sine wave can be generated from luts by hand or nco compiler. --- Quote End --- how LUTs can store signal ,and how to convert gaussan from matlab to vhdl,i đon't understand ??? how can generate sine ...

(orange curve). Each pulse has a duration of 8 μs which leads to a whole period of 16×8=128 μs as shown with the vertical cursors in the figures. Note that the baseband pulse can have any arbitrary wave shape as we have both rectangular (top) and Gaussian (bottom) pulses in ...
