Pilot tone aided measurements to extend the bandwidth of radio frequency applications
(Elsevier B.V., 2016)
A technique to extend the effective measurement bandwidth of a non-coherent vector receiver is presented. This bandwidth extension technique relies on the use of a pilot signal (known a priori), which is added on the signal ...
Beamforming echo-localization system using multitone excitation signals
(Institute of Electrical and Electronics Engineers Inc., 2017)
Determining the position of a target is the central issue in several engineering problems, from computer vision to sonar or radar systems. Echo-localization systems use the reflected sound waves to extract information from ...

Machine Learning Classifier Approach with Gaussian Process, Ensemble boosted Trees, SVM, and Linear Regression for 5G Signal Coverage Mapping
This article offers a thorough analysis of the machine learning classifiers approaches for the collected Received Signal Strength Indicator (RSSI) samples which can be applied in predicting propagation loss, used for network ...
Snapshots of conformational changes of NtrX receiver domain shed light into its signal transduction mechanism
(Elsevier, 2015-10)
Brucella abortus is an important pathogenic bacterium that has to overcome oxygen deficiency in order to achieve a successful infection. Previously, we proved that a two-component system formed by the histidine kinase NtrY ...
Full flexible five-port receiver
(2010)
This paper reports the architecture of a five-port receiver without vector base circuit generators in which three antennas provide three phase-shifted copies of the received signal. A 2.4 GHz prototype was implemented for ...
Feedforward carrier recovery for polarization demultiplexed signals with unequal signal to noise ratios
(Optical Soc AmerWashingtonEUA, 2009)
Improving signal-strength aggregation for mobile crowdsourcing scenarios
(MDPI, 2021)
Due to its huge impact on the overall quality of service (QoS) of wireless networks, both academic
and industrial research have actively focused on analyzing the received signal strength in
areas of particular interest. ...
