Abstract
Even though broadband signaling and reception is often employed in practice for communication over time- and frequency-dispersive channels, existing receiver designs do not fully exploit the advantage of broadband signaling. We introduce a framework for time-frequency processing that is dictated by a canonical characterization of linear dispersive channels and fully utilizes the advantage of broadband signaling. The framework is based on processing in a natural time-frequency subspace defined by orthogonal time-frequency shifted copies of the transmitted broadband waveform. It generalizes existing receivers and suggests new designs that promise substantially improved performance compared to existing systems.
