Abstract
In this work, we consider the problem of channel es- timation by using the recently developed theory for sampling of signals with a finite rate of innovation (1). We show a framework which allows for lower than Nyquist rate sampling applicable for timing and channel estimation of both narrowband and wideband channels. In certain cases we demonstrate performance exceeding that of algorithms using Nyquist rate sampling while working at lower sampling rates, thus saving power and computational com- plexity.Keywords
