About
Tomohisa Wada is a leading researcher in underwater acoustic communications, specializing in Orthogonal Frequency Division Multiplexing (OFDM) systems for robotic and sensor networks. His core contributions address the critical challenge of Doppler shift in vertical underwater links—such as between seafloor robots and surface vessels—where time-varying velocity distorts signals. Wada pioneered symbol-by-symbol Doppler compensation using continual pilots, enabling reliable data transmission despite rapid velocity changes. He also developed adaptive transceiver architectures and frequency-domain diversity combiners with impulsive noise cancellation, significantly improving link robustness in harsh underwater environments. His work on the Underwater Small Area Acoustic Network (USAAN) prototype demonstrated bidirectional OFDM-based control of underwater robots, a practical step toward autonomous exploration. With over 28 citations across his most influential papers, Wada’s research directly supports remote-operated vehicles (ROVs), autonomous underwater vehicles (AUVs), and diver communication systems. His innovations in Doppler-resilient OFDM and noise mitigation continue to shape the design of next-generation underwater wireless networks for marine resource exploration and real-time robot control.
