Dear All, I am really strugling to write a nice program giving me the curve of the PSD of a random data. If I use the FFT function I will get a descreat representation and not smooth and continues like I found in some publication. Could any one help me with some matlab code to plot a continues PSD. Thanks very much regards

I'm trying to plot the power spec of a set of normally distributed random values. I'm told it should look like a straight line. However, I'm not seeing this. I'm seeing a 'spike' at the beginning, or at the end, depending on the shift. Any thoughts? As you can see, I'm a begin

Hi all!! I implemented in Matlab some different ZF equalizations, but I should change the input signal froma random [+1/-1] signal to a QPSK or BPSK signal (choosing number of samples, oversampling and so on..), but I have no idea of how doing it. Could anyone give me some advices or some code-examples? Thank you all in advance, Ella PS:here there

I am using an AR model to estimate a noise sequency, I should be able to simulate a longer sequency of the noise. I have tried to use predict command, but the sequency looks different. I have also tried too use a long random noise sequency and used that with the model, but then frequencies don't match. Is there any methhod I could solve this problem,

I have a data file that I'd really like to load into matlab because it is very convient for me to do the analysis in matlab. Normally between textread and load I don't have a problem doing this, but this file contains 'random' strings every once in a while. Most of the file is number
