variable-band-width filter

The space-time processing principle of antenna array for UWB pulse reception is studied. Aiming at the realization problem of highly accurate variable delay circuits ( VDC), a combination of digital lines and fractional sample delay compensation filter ( FDCF) for beamforming in time domain is proposed.
