Model-based deep unfolding for robust and efficient free-space optical channel estimation under turbulence and impulsive jamming
Abstract Atmospheric turbulence makes free-space optical (FSO) channels fluctuate, and a receiver that does not track them pays in bit errors. As a controlled simulation study, we address pilot-aided channel estimation for an on–off keying direct-detection link with temporally correlated Gamma–Gamma fading and an on–of...
