I have two signals $x$ (see below) and $k$ (obtained by giving circular shift of 106.5849 in $x$). Before I take FFT of both ($x$ and $k$) I want to do window analysis on them.
Kindly can some one please help, How I can choose the window?
After applying FFT I will find Cross power spectrum of both $f$ domain signals.
t=0*10^-9:4*10^-9:150*10^-9; fc=5*10^6; xi=sin(2*pi*fc*t); yi=154*10^-9:4*10^-9:2000*10^-9; y=yi*0; x=[xi y]; k=fshift(x,106.5849);
My eventual aim is to implement the following diagram.
