CFFT is a radix-4 fast Fourier transform (FFT) core with configurable data width and
a configurable number of sample points in the FFT.
Twiddle factors are implemented using the CORDIC algorithm, causing the gain of the
CFFT core to be different from the standard FFT algorithm. This variation in gain
is not important for orthogonal frequency division modulation (OFDM) and demodulation.
The gain can be corrected, to that of a conventional FFT, by applying a constant
multiplying factor.
