The compressive sensing theory is implemented by means of analog-to-information converter (AIC) that provides a digitized and compressed output $y$ directly from its analog input signal $x$ . A reconstruction algorithm, in turn, is needed to obtain a

Background Controlling the COVID-19 outbreak in Brazil is a challenge due to the population’s size and urban density, inefficient maintenance of social distancing and testing strategies, and limited availability of testing resources. Objective The

Chipless RFID tags were introduced as a low cost alternative to IoT identification systems. However, to make them competitive, there is a need to increase their coding capacity. C-sections based on group delay are a promising coding technique that st

In Wireless Sensor Networks cooperation between network elements can be used to improve the signal-to-noise ratio for a given node. In this work we propose an open loop distributed beamforming system for Wireless Sensor Networks. Our approach is insp

Analog-to-Information Converter (AIC) is the physical implementation of Compressed Sensing (CS) systems to digitize signals directly from the analog domain. Due to non-idealities of components AIC hardware needs a calibration step to adjust parameter

To identify and predict anomalous power consumption, this paper proposes a method based on Long Short-Term Memory (LSTM) and Negative Selection technologies that anticipates the occurrence of anomalies in power consumption, and to provide useful info
