Detailed Description

Compute intermediate samples between signal samples x(k*Ts).

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.

gr_complex gri_mmse_fir_interpolator_cc::interpolate (  const gr_complex  input[], float  mu )

compute a single interpolated output value. input must have ntaps() valid entries. input[0] .. input[ntaps() - 1] are referenced to compute the output value. mu must be in the range [0, 1] and specifies the fractional delay. Returns: the interpolated input value.
