Hi Kerry,Thanks a lot for sharing this example, and the Volterra code!The cross-spectrum based example looks more easier of implementation/test in practice,...
Hi kschutz,Yes you are right, with my method I can only estimate the frequency amplitude response while not phase response.For the method you mentioned, I feel...
Hi Robert,See the latest post from Hoffmann. He has pointed out my bug, and I further confirm that the IFFT of PSD must be real with a simple proof.Regards,Hao
Hi Hoffmann,Thanks for finding the bug!!! I would like confirm that the IFFT of correct PSD must be real with a simple proof:If the input signal x is real (like...
Hi kaz,A good idea to use chirp signal as input.One another problem in my application is I want to separately characterize the Tx and Rx side frequency response....
Hi kaz,Background of my application is an optical communication system, I want characterize the receiver side frequency response (only frequency amplitude).For...
Hi Robert,Thanks for sharing the link.I still can't ensure if the conclusion "the imaginary part should be at or close to zero" generally holds with some proof. Let's...
Hi omersayli,Thanks for your reply. In the example script the imaginary part of h is very small compared to real part, but I am not sure if the conclusion holds...
