Thank you for your help. I read my post again and I admit that it was
really confusing. So, I will try to make my question more clear.
I am trying to make a multiplexer using IFFT. Input signal is array of
complex numbers which represents complex weight for corresponding
sinusoidal basis function
Output of IFFT block is summation of N orthogonal sinusoids. These
sinusoids each have different frequency and the lowest is 0 (DC). In
reality output is array of complex numbers which represent complex
weight for corresponding sinusoidal basis function. I neeed to know
how to present output
