N2 - In this paper, we propose a frequency-domain characterization of shallow water systems based on normal-mode acoustic processing that is applicable to a large class of signals. After studying the dispersive characteristics of this system, we propose a matched transmission waveform and receiver structure. The design uses a warping technique and the system characteristics to obtain time-dispersion diversity. Simulation results demonstrate that the system characterization and receiver schemes can improve processing performance.
