Abstract

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).
