ofdm
====


 A module to compute the Fast Fourier Transform and its inverse, thus enabling
OFDM transmission. As the scaling of the output of a OFDM is difficult, there
is a manual scaling-factor that can be chosen by the programmer.


ofdm_rcv
--------

 This module will receive the time domain samples and compute their FFT's
@size_pot is the size of the input as a power of two.

Inputs:
	SYMBOL_COMPLEX

outputs:
	SYMBOL_COMPLEX

Config:
	mult<double>: 1
		Some multiplicative factor, must be the same as in fft_send.
		In fact it is more like a division factor, but well, I chose to
		take the same name as in fft_send...

	size_pot<int>: 8
		The size of the fft will be 2 ^ size_pot

Inputs:
	SYMBOL_COMPLEX

outputs:

Config:
	mult<double>: 1
		Some multiplicative factor. Should be the same as in fft_rcv

	size_pot<int>: 8
		The total size will be 2 ^ size_pot
