Underwater Acoustic Channel Library
Zhengnan Li, Mandar Chitre, Diego A. Cuji +4
The development of communication systems critically depends on realistic channel models, yet there are no widely accepted standards in the underwater acoustic communications commun…
A Switching Beamformer for Highly Non-Stationary Environments
Manan Mittal, Ryan M. Corey, John R. Buck +1
Adaptive beamforming is a cornerstone of array signal processing, yet its performance often collapses in the face of complex, rapidly changing interference. When interferers appear…
Time Segmented Beamforming via Dynamic Programming: Theory and Implementation
Manan Mittal, Ryan M. Corey, Diego Cuji +2
In dynamic acoustic environments with time-varying interferers, effective beamforming requires identifying stationary regions over time. The Capon beamformer, a whitened matched fi…
Transmit Beamforming for High-Rate Underwater Acoustic Communications
Diego A. Cuji, Andrew C. Singer, Milica Stojanovic
Transmit beamforming for underwater acoustic communications is challenging because channel state information must be obtained through feedback and may be noisy or outdated. In this…
