In this paper, we propose a discrete characterization of dispersive time-varying systems. Based on a unitary warping relation with the narrowband system model, we formulate a representation that decomposes the system output as a weighted superposition of sampled signal transformations that reflect the dispersive system characteristics. Such discrete representations can be important in designing waveforms for transmission through dispersive systems with improved processing performance. We demonstrate the usefulness of our proposed model by applying it to a shallow water acoustic environment characterized by nonlinear frequency dispersions. |
