About

Tran Minh Hai is a researcher specializing in underwater acoustic communications, with a particular focus on orthogonal frequency-division multiplexing (OFDM) systems for challenging vertical-link environments. His major contributions center on developing robust transceiver architectures that can handle time-varying Doppler shifts—a critical problem when communicating between surface vessels and submerged robots. In his most cited work, "An Acoustic OFDM System with Symbol-by-Symbol Doppler Compensation for Underwater Communication" (2016, 10 citations), Hai introduced a novel method for estimating dynamic Doppler shifts using continual pilots, enabling reliable real-time compensation. His earlier foundational paper, "A transceiver architecture for ultrasonic OFDM with adaptive Doppler compensation" (2015, 8 citations), demonstrated practical solutions for scenarios where velocity changes gradually but unpredictably. Hai's work directly addresses the unique challenges of underwater wireless links, where multipath propagation and Doppler effects severely degrade performance. By enabling stable, high-rate communication between sea-bottom robots and surface ships, his research has important implications for ocean exploration, underwater surveillance, and autonomous underwater vehicle operations. His adaptive Doppler compensation techniques represent a significant step forward in making underwater OFDM systems practical for real-world deployment.
