Special Issue Information

Dear Colleagues,

Underwater acoustic communications (UWACs) play significant roles in diverse sectors such as underwater ocean exploration, marine research, environmental monitoring, and military applications like submarine communications. Academia and industries have conducted research and development (R&D) in UWACs to enhance marine innovations intelligently. However, the unique characteristics of underwater environments pose major obstacles to the development of wireless communication and networking systems due to the hostile environment, strong signal attenuation, multipath dispersion, Doppler shift, mobility, link and topology dynamics, etc. In recent times, both academia and industry have made notable efforts to overcome these challenges. Thus, this Special Issue aims to showcase the latest findings, developments, and reviews in the field of UWACs while providing new ideas and technologies to drive further R&D in UWACs. This Special Issue's scope encompasses but is not restricted to:

  • Underwater channel modeling, estimation and characterization;
  • Underwater ranging, localization and tracking;
  • Underwater surveillance and monitoring;
  • Underwater network optimization and resource allocation;
  • Underwater covert communication;
  • Machine/deep learning-based underwater communication;
  • Underwater Internet of Things (UIoT).

This paper presents an underwater biomimetic covert acoustic communication system that achieves high covertness and a high data rate by mimicking dolphin group whistles. The proposed method uses combined time–frequency shift keying modulation with continuous varying carrier frequency modulation, which mitigates the interference between two overlapping multiple whistles while maintaining a high data rate. The data rate and bit error rate (BER) performance of the proposed method were compared with conventional underwater covert communication through an additive white Gaussian noise channel, a modeled underwater channel, and practical ocean experiments. For the covertness test, the similarity of the proposed multiple whistles was compared with the real dolphin group whistles using the mean opinion score test. As a result, the proposed method demonstrated a higher data rate, better BER performance, and large covertness to the real dolphin group whistles. Full article
