There is a simple code in below that I prepared for understandable a question. My purpose is recover original complex signal after FFT process in Matlab.
As you understand from code, I created 1x128 complex vector. After I implement IFFT process this code. Then again I implemented FFT process for recover original complex code.
Code:
a1 = linspace(0.1,0.6,128);
a2 = linspace(0.2,0.6,128);
cn = complex (a1,a2); ifcn = ifft(cn,128,2);
fcn = fft(ifcn,128,2);
%difcn = fcn - cn;%Checking difference between original and after fft
There are few questions in my mind.
-Is ıt possible recover original complex signal after IFFT and FFT, If it is possible please could you describe me?
-In my project code normally has more deatils also I will implement after IFFT AWGN noise to signal. If this code works properly I am thinking use the this code.
Thanks in Advance
