Robust Pricing Mechanism for Resource Sustainability Under Privacy Constraint in Competitive Online Learning Multi-Agent Systems

ICASSP 2020accepted

We consider the problem of resource congestion control for competing online learning agents under privacy and security constraints. Based on the non-cooperative game as the model for agents' interaction and the noisy online mirror ascent as the model for the rationality of the agents, we propose a n…

Probabilistic analysis of tone reservation method for the PAPR reduction of OFDM systems

ICASSP 2017accepted

High peak values of transmission signals in wireless communication systems lead to wasteful energy consumption and degradation of several transmission performances. We continue the theoretical contributions made by B. and Farell [1, 2] towards the understanding of peak value reduction, using the str…

On the decay - and the smoothness behavior of the Fourier transform, and the construction of signals having strong divergent Shannon sampling series

ICASSP 2016accepted

In this work, we show by means of the technique inspired by the Banach-Steinhaus Thm., that typically the Fourier transform of an integrable signal decays arbitrarily slowly toward the infinity, and has an arbitrary weak worst continuity/smoothness behaviour. However, the corresponding characterizat…
