Abstract

One of the major challenges at the physical layer of an ultra-wideband (UWB) network is the accuracy and speed of the synchronization and channel estimation tasks. Especially in ad hoc multi-access scenarios, acquiring timing and channel information blindly is instrumental for user separation and band-width efficient demodulation. Relying on intermittently transmitted asymmetric pulse-amplitude modulated (PAM) signals, we derive novel blind timing and channel estimators for UWB point-to-point and multi-access communication links for use in ad hoc networks. Both intersymbol interference (ISI)-free as well as ISI channels are considered. Comparisons are provided and performance of the resultant algorithms is evaluated analytically and with bit-error rate (BER) simulations.
