Propagation-Constrained Stochastic Modeling and Robust Recursive Estimation of Air-to-Underwater ELF Signals Under Depth-Evolving Alpha-Stable Disturbances
Air-to-underwater extremely low frequency (ELF) signal recovery requires a receiver that accounts for both cross-medium attenuation and impulsive interference. Seawater weakens the desired electromagnetic waveform while altering the tail behavior that remains observable within the receiver bandwidth. Conventional recur...
