'Rafael Aguilar-Gonzalez' 'Francesca Cuomo'] In this work, a novel multiband spectrum sensing technique is implemented in the context of cognitive radios. This technique is based on multiresolution analysis (wavelets), machine learning, and the Higuchi fractal dimension. The theoretical contribution was developed…

The number of applications of low-power wide-area networks (LPWANs) has been growing quite considerably in the past few years and so has the number of protocol stacks. Despite this fact, there is still no fully open LPWAN protocol stack available to the public, which limits the flexibility and ease of integration of…

The paper presents a framework to emulate spacecraft orbits using GNSS hardware in the loop that enables the evaluation of new orbital positioning algorithms. The framework software generates the spacecraft orbit and the GNSS signals, including the most common perturbations. These signals are modulated and transmitted…

—Of late, Software Defined Radio (SDR) approach has become an effective means to design high data rate wireless systems for a range of applications. There are methods with which low cost SDR based 4th generation (4G) or long term evolution (LTE) systems can be designed. Using low cost Raspberry Pi systems, the SDR…

The article presents a method which organizes men-in-the-middle attack and penetration test on Bluetooth Low Energy devices and ZigBee packets by using software define radio with sniffing and spoofing packets, capture and analysis techniques on wireless waves with the focus on BLE. The paper contains the analysis of…

—This paper reports an implementation of the PHY specifications of the IEEE 802.15.4 standard for the frequency band 868/915 MHz on a Software Defined Radio (SDR) platform. This standard is defined for low power, low data rate and low cost wireless networks. These specifications are used by the Zigbee technology for…

'R. Michael Barts' 'Ashwin Panicker' 'Özgür Özdemir' 'İsmail Güvenç'] Abstract—As new use cases are emerging for unmanned aerial systems (UASs), advanced wireless communications technologies and systems need to be implemented and widely tested. This requires a flexible platform for development, deployment, testing and…

In longitudinal observations of animal groups, the goal is to identify individuals and to reliably detect their interactive behaviors, including their vocalizations. However, to reliably extract individual vocalizations from their mixtures and other environmental sounds remains a serious challenge. Promising approaches…
