Conditions for the existence of a generalization of Rényi divergence
Rui F. Vigelis, Luiza H. F. de Andrade, Charles C. Cavalcante
We give necessary and sufficient conditions for the existence of a generalization of Rényi divergence, which is defined in terms of a deformed exponential function. If the underlyi…
Channel Parameter Estimation for Millimeter-Wave Cellular Systems with Hybrid Beamforming
Fazal-E-Asim, Felix Antreich, Charles C. Cavalcante +2
To achieve high data rates defined in 5G, the use of millimeter-waves and massive-MIMO are indispensable. To benefit from these technologies, an accurate estimation of the channel…
Rank-one Detector for Kronecker-Structured Constant Modulus Constellations
Fazal-E-Asim, André L. F. de Almeida, Martin Haardt +2
To achieve a reliable communication with short data blocks, we propose a novel decoding strategy for Kronecker-structured constant modulus signals that provides low bit error ratio…
Properties of a Generalized Divergence Related to Tsallis Relative Entropy
Rui F. Vigelis, Luiza H. F. de Andrade, Charles C. Cavalcante
In this paper, we investigate the partition inequality, joint convexity, and Pinsker's inequality, for a divergence that generalizes the Tsallis Relative Entropy and Kullback-Leibl…
New Metric and Connections in Statistical Manifolds
Rui F. Vigelis, David C. de Souza, Charles C. Cavalcante
We define a metric and a family of -connections in statistical manifolds, based on -divergence, which emerges in the framework of -families of probability distributions. T…
Smoothness of the Orlicz Norm in Musielak-Orlicz Function Spaces
Rui F. Vigelis, Charles C. Cavalcante
In this paper, we present a characterization of support functionals and smooth points in , the Musielak-Orlicz space equipped with the Orlicz norm. As a result, criterion…
