Evaluation of Signal Waveform Patterns for SSMS Underwater Acoustic Communication

While high-speed and large-capacity underwater acoustic communication has recently been improved, research and development of communication systems that can withstand low transmission rates and low signal-to-noise ratio environments has also been studied. We presented stretchable symbols with multiple sequences (SSMS) that is highly tolerant to harsh communication environments such as Doppler shift, terminal oscillation, and acoustic wave reflection. In this study, we present the performance evaluation of the SSMS system in terms of waveform data size and low probability of detection for various kinds of waveform patterns.
