Consistent Estimation of a Class of Distances Between Covariance Matrices
Roberto Pereira, Xavier Mestre, Davig Gregoratti
This work considers the problem of estimating the distance between two covariance matrices directly from the data. Particularly, we are interested in the family of distances that c…
Asymptotics of Distances Between Sample Covariance Matrices
Roberto Pereira, Xavier Mestre, David Gregoratti
This work considers the asymptotic behavior of the distance between two sample covariance matrices (SCM). A general result is provided for a class of functionals that can be expres…
Mathematical Properties of the Zadoff-Chu Sequences
David Gregoratti, Xavier Arteaga, Joaquim Broquetas
This paper is a compilation of well-known results about Zadoff-Chu sequences, including all proofs with a consistent mathematical notation, for easy reference. Moreover, for a Zado…
Floor Map Reconstruction Through Radio Sensing and Learning By a Large Intelligent Surface
Cristian J. Vaca-Rubio, Roberto Pereira, Xavier Mestre +4
Environmental scene reconstruction is of great interest for autonomous robotic applications, since an accurate representation of the environment is necessary to ensure safe interac…
User Clustering for Rate Splitting using Machine Learning
Roberto Pereira, Anay Ajit Deshpande, Cristian J. Vaca-Rubio +5
Hierarchical Rate Splitting (HRS) schemes proposed in recent years have shown to provide significant improvements in exploiting spatial diversity in wireless networks and provide h…
Exclusive Group Lasso for Structured Variable Selection
David Gregoratti, Xavier Mestre, Carlos Buelga
A structured variable selection problem is considered in which the covariates, divided into predefined groups, activate according to sparse patterns with few nonzero entries per gr…
