How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

A selective review of the most recent developments in the estimation of the covariance matrix with a number of samples smaller than the ambient dimension is presented. In particular, estimators are considered for low rank and sparse structures, paying special attention to the algorithms most used in practice. Estimators that resort to the use of cl...

Methods based on order statistics are often used in finance, quality control, data and signal processing, especially when signals of interest are immersed in impulsive noise. These allow to include rank information by increasing the dimension of the problem. In large dimension problems, we are usually required to know only the second order statisti...

At the reception of wireless communications the wavelet packet-division multiplexing (WPDM) has shown susceptibility to multipath fading. Inspired by WPDM, this paper proposes a new scheme of multiplexing, which has been called “Dynamic Wavelet Packet-Division Multiplexing (DWPDM)”, that allow adapt to the channel conditions and improve their perfo...

This article presents the results of extensive simulation about the multiuser transmission technique, named Wavelet Packet Division Multiplexing (WPDM). Its advantages are the capability of multiple signals transmission, in a flexible and robust form. The signals of the multi users are coded by bases functions of the wavelet packet (WP) family. The...
