Removing redundant frequency data from 4/3 oversampled sub-bands. An FFT transforms the time-domain data to the frequency domain, where 1/8 of the samples are cropped from each edge to eliminate filter roll-off artifacts, yielding a clean 128 MHz band before an IFFT returns the data to the time domain.
