Integrated Sensing and Communications with Affine Frequency Division Multiplexing
Ali Bemani, Nassar Ksairi, Marios Kountouris
Integrated sensing and communications (ISAC) is regarded as a key technology in next-generation (6G) mobile communication systems. Affine frequency division multiplexing (AFDM) is…
Copula-based Estimation of Continuous Sources for a Class of Constrained Rate-Distortion-Functions
Giuseppe Serra, Photios A. Stavrou, Marios Kountouris
We present a new method to estimate the rate-distortion-perception function in the perfect realism regime (PR-RDPF), for multivariate continuous sources subject to a single-letter…
On the Computation of the Gaussian Rate-Distortion-Perception Function
Giuseppe Serra, Photios A. Stavrou, Marios Kountouris
In this paper, we study the computation of the rate-distortion-perception function (RDPF) for a multivariate Gaussian source under mean squared error (MSE) distortion and, respecti…
State-aware Real-time Tracking and Remote Reconstruction of a Markov Source
Mehrdad Salimnejad, Marios Kountouris, Nikolaos Pappas
The problem of real-time remote tracking and reconstruction of a two-state Markov process is considered here. A transmitter sends samples from an observed information source to a r…
An Information-Theoretic Analog of the Twin Paradox
Mladen Kovačević, Iosif Pinelis, Marios Kountouris
We revisit the familiar scenario involving two parties in relative motion, in which Alice stays at rest while Bob goes on a journey at speed along an arbitrary trajectory and…
Indirect Rate Distortion Functions with -Separable Distortion Criterion
Photios A. Stavrou, Yanina Shkel, Marios Kountouris
We consider a remote source coding problem subject to a {distortion function}. Contrary to the use of the classical separable distortion criterion, herein we consider the more gene…
