#include <gr_mmse_fir_interpolator.h>
This implements a Mininum Mean Squared Error interpolator with 8 taps. It is suitable for signals where the bandwidth of interest B = 1/(4*Ts) Where Ts is the time between samples.
Although mu, the fractional delay, is specified as a float, it is actually quantized. 0.0 <= mu <= 1.0. That is, mu is quantized in the interpolate method to 32nd's of a sample.
