Hi, I have a MATLAB related question. I have a periodic signal loaded into Matlab and i am trying to estimate the Autocovariance of it by using the xcov command. This gives me an output that i store as a variable. I'd just like to know if anyone knows why: a) the xcov matrix is twice as long as the original signal and; b) how can i, from the xcov result see the periodicity of the wave...

Hello, I am testing different OFDM Channel estimation (CE) approaches by modelation in Simulink, and I am having a problem, that might be stupid but is taking to much of my time without finding a solution. My problem comes when I want to compare several methods to ideal LMMSE CE. I know the channel from measurements, so I have the attenuation coefficients for each subcarrier, i.e. the column...
