Hi, I'm kind of newbie in Matlab so I want to excuse wether the q=FCestion is too simple... I'm working with a link of two antennas and I want to obtain the ifft of a parameter. With an antenna design software I obtain the amplitude and phase in the frequency domain of such parameter. Then I have to construct the complex parameter with the amplitude and phase and finally I have to apply the ifft. If my frequency domain goes from fmin (different from 0 Hz) to fmax with a certain fstep, when I apply the real(ifft(parameter)) I have to add zeros to the complex parameter in the frequency domain from 0 Ghz to fmin and after apply the real(ifft(parameter))? Can I apply it directly or I have to do something else before? And how is the time domain, that is, when I obtain the ifft I don't know how to find out tmin, tmax and tstep, the time axis. The number of samples plays a role, I suppose... Thanks a lot in advance. Sandra F.R.
