About
Rie Saotome is a leading researcher in underwater acoustic communications, specializing in Orthogonal Frequency Division Multiplexing (OFDM) systems for robotic and autonomous vehicle control. Her work addresses the critical challenge of reliable data transmission in vertical underwater links—connecting seafloor robots to surface mother ships—where time-varying Doppler shifts severely degrade performance. Saotome’s major contributions include developing symbol-by-symbol Doppler compensation techniques using continual pilots, and designing adaptive transceiver architectures that track velocity changes in real time. Her 2016 paper on acoustic OFDM with Doppler compensation (10 citations) and her 2015 work on adaptive Doppler compensation (8 citations) are foundational references in the field. She also pioneered a frequency-domain diversity combiner with an impulsive noise canceller (7 citations), improving robustness in noisy underwater networks. Notably, Saotome led the development of a prototype wireless underwater robot control system using a 32 kHz bandwidth Underwater Small Area Acoustic Network (USAAN), demonstrating bidirectional TDD-OFDM control of an actual underwater vehicle. Her research directly enables practical applications in marine resource exploration, ROV/AUV operations, and diver communication, with her combined work accumulating over 28 citations and establishing her as a key innovator in underwater wireless networking.
