Performance of Ultra-Wideband (UWB) communication systems can be enhanced by collecting multipath diversity gains, once the channels are acquired at the receiver. In this paper, we develop a novel pilot waveform assisted modulation (PWAM) scheme that is tailored for power-limited UWB communications, and can be implemented in analog form. The PWAM parameters are designed to jointly optimize performance, and information rate. The resulting transmitter design also minimizes the mean-square error (MSE) of channel estimation, and thereby achieves the Cramer-Rao Lower Bound (CRLB).
