Technical Examples

A system and method of improving signal to noise ration (SNR) in a fixed point fast Fourier transform (FFT/IFFT) generates from sample inputs and a twiddle factor butterfly outputs for each stage; scales the butterfly outputs of this stage from a predicted normalization scale factor to obtain the maximum butterfly output without overflow from this stage; determines from the butterfly outputs of this stage the minimum normalizing exponent for the butterfly outputs of this stage and predicts a normalization scale factor of the next stage from the minimum normalizing exponent of this stage and a stage guard scale value to obtain the maximum butterfly output without overflow from that next stage.
