Channel estimation plays an important role in underwater acoustic communications, with applications in phase-coherent modulation schemes and preparation of replay channels. Quantifying the estimation error is a challenge, however, as the true channel remains unknown. This paper introduces the channel replay error (CRE) as the difference between a t...

In this talk, we review our recent efforts to formulate, calibrate and leverage compact physics-compliant models of wave scattering in arbitrarily complex linear systems parametrized by programmable metasurfaces (also known as reconfigurable intelligent surfaces, RISs). RISs are foreseen to enable the paradigm shift toward smart radio environments....

This paper tackles the intricate challenge of channel estimation (CE) and symbol detection in high-mobility scenar- ios for orthogonal time frequency space (OTFS) systems. We introduce a novel partially superimposed pilots (PSP) pattern, strategically balancing computational complexity and CE ac- curacy by partially superimposing pilots and data sy...

Orthogonal Time Frequency Space (OTFS) is a promising modulation scheme that works in the delay-Doppler (DD) domain, offering resistance to frequency selective fading and time-varying channels. Thus, OTFS channel estimation assumes great significance for successful transmission. Typically, it requires allocating pilots in the DD domain, which often...

Secrecy encoding for remote state estimation in the presence of adversarial eavesdroppers is a well studied problem. Typical existing secrecy encoding schemes rely on the transmitter's knowledge of the remote estimator's current performance. This performance measure is often shared via packet receipt acknowledgments. However, in practical situation...

The phase noise (PN) generated by the oscillators limits the link performance of radio frequency (RF) transmission systems. In OFDM, the PN induces the intercarrier interference (ICI) which needs to be addressed when one expects using higher order modulations. In this work, we propose a new algorithm called time domain filter (TDF). It consists in ...

The phase noise (PN) generated by the oscillators limits the link performance of radio frequency transmission systems. In OFDM, the PN induces intercarrier interference (ICI) which needs to be addressed to limit spectral efficiency penalty. In this work, we propose a new algorithm called time domain filter (TDF). It consists in mitigating the ICI b...

In this article, we consider the problem of remote state estimation of a Gauss-Markov process, where a sensor can, at each discrete time instant, transmit on one out of M different communication channels. A key difficulty of the situation at hand is that the channel statistics are unknown. We study the case where both learning of the channel recept...
