Rational dither modulation: a high-rate data-hiding method invariant to gain attacks
A novel quantization-based data-hiding method, called Rational Dither Modulation (RDM), is presented. This method retains most of the simplicity of the conventional dither modulation (DM) scheme,Expand

Performance analysis of a distributed resource allocation scheme for D2D communications
tl;dr
In this paper we formulate the joint mode selection, scheduling and power control task as an optimization problem that we first solve assuming the availability of a central entity. Expand

Low-complexity predictive lossy compression of hyperspectral and ultraspectral images
tl;dr
We propose a low-complexity lossy hyperspectral image compression scheme based on prediction, uniform-threshold quantization, and rate-distortion optimization. Expand

On the Convergence and Optimality of Reweighted Message Passing for Channel Assignment Problems
tl;dr
We provide proof of the convergence and the optimality of the reweighted message passing (ReMP) algorithm when applied to solve BWBM problems in a distributed fashion. Expand

  • 15 September 2016
tl;dr
We propose a distributed power allocation scheme for D2D OFDMA communications and, in particular, we consider the two operating modes amenable to a distributed implementation: dedicated and reuse modes. Expand

Radio resource allocation problems for OFDMA cellular systems
tl;dr
We address the problem of resource allocation in the downlink of a multi-cellular OFDMA system by performing dynamic resource allocation. Expand

Message Passing Resource Allocation for the Uplink of Multi-Carrier Multi-Format Systems
tl;dr
We propose two novel distributed resource allocation (RA) schemes for the uplink of a cellular multi-carrier multi-format system based on the message passing (MP) technique. Expand

Benchmarking Practical RRM Algorithms for D2D Communications in LTE Advanced
tl;dr
Device-to-device (D2D) communication integrated into cellular networks requires to revisit and modify the existing radio resource management and power control (PC) techniques in order to fully realize the potential of the proximity and reuse gains and to limit the interference to the cellular layer.
