N2 - In this paper, we investigate the dispersive characterization of shallow water environments for acoustic transmissions, and we develop a time-varying system representation to model its dispersive propagation characteristics. We also obtain the discrete model of this representation using a transform-based approach or by nonlinearly warping the discrete time-frequency model of narrowband environments. Using this discrete model in a shallow water communication application, we design a wideband time varying waveform to match the dispersive nature of the environment. As we demonstrate with numerical results, the design can provide dispersive Doppler diversity by employing maximal ratio combining techniques.
