Optimal pilot waveform assisted modulation for ultrawideband communications.

Optimal pilot waveform assisted modulation for ultrawideband communications.

Ultrawideband (UWB) transmissions induce pronounced frequency-selective fading effects in their multipath propagation. Multipath diversity gains can be collected to enhance performance, provided that the underlying channel can be estimated at the receiver. To this end, we develop a novel pilot wavef...
