Beamforming algorithm in the minimum variance distortionless response beamformer and give a diagram of conventional beamforming and MVDR two waveforms.
Generalized UWB-ATR receiver is proposed, in which the local template waveform is computed as the average of the channel responses to nonfinite M transmitted reference pulses.
They also tried time-domain reflectometry - a method of transmitting a waveform through the cable and measuring the reflections - but the results weren't conclusive.
