We propose a non-data-aided adaptive beamforming algorithm based on Widely Linear
(WL) processing techniques and the Auxiliary Vector Filtering (AVF) algorithm for non …

In the context of secure wireless communications, pseudo-noise (PN) masking of transferred
data has proven to be an effective technique against eavesdropping (notable examples are …

Pseudo-noise (PN) masking is regarded as an effective means to combat data
eavesdropping (for example in military-grade communications or positioning systems). At …

The aim of this thesis is to investigate key issues encountered in the design of transmission
schemes and receiving techniques for Ultra Wideband (UWB) communication systems …

The objective of this work is the development of a solid theoretical and algorithmic
framework for outlier-resistant L 1-norm Principal Component Analysis (PCA). PCA is the …

In many applications of digital signal processing, signal characteristics could change. This
requires the utilization of adaptive filters. The Recursive Least Squares (RLS) algorithm has …

Diversas aplicações utilizam arranjos de sensores, por exemplo: radares; sonares;
comunicações wireless; e aplicações de conformação de feixe-também conhecido …
