Abstract

In this paper, we propose an underwater acoustic communication with hyperbolic frequency modulated waveforms. The first process is modulating a hyperbolic chirp´s slope by binary data with a silence representing 0, and a hyperbolic frequency modulated pulse representing 1. The received signal is demodulated by matched filtering of received signal and one hyperbolic chirp pulse. The binary `1´ is decided when the output of the matched filter is greater than the reference threshold for decision. Simulation was performed to evaluate the performance of the proposed method.
