In the event of a disaster or emergency, it is not uncommon for the dedicated communication infrastructure to become damaged or weakened. This is not just an inconvenience but rather a monumental problem for first responders or any kind of disaster ...

With the progression of technology as integrated into daily life, physical tech has become increasingly embedded or hidden from the user’s view. Because of this design change, many of the aesthetics that previously defined everyday technology have ...

This paper presents a Software Defined Radio (SDR) implementation in C++ of a Multiple Input Multiple Output (MIMO) transceiver platform using the open-source 5G physical layer free5GRAN. The platform evaluates the processing latency of physical layer ...

We present a set of experiments utilizing wideband real-time adaptive full-duplex (FD) radios, demonstrating simultaneous transmission and reception on the same frequency channel. Each FD radio consists of a circulator-based antenna interface, a switched-...

Supervisory control and data acquisition (SCADA) systems were designed to be open, robust, and easy to operate and repair, but not necessarily secure. In recent years, there have been multiple successful attacks targeting SCADA systems. Most of ...

In this paper, we present SDR-LoRa, a full-fledged SDR implementation of a LoRa transmitter and receiver. First, we reverse-engineer the LoRa physical layer (PHY) functionalities, including the procedures of packet modulation, demodulation, and preamble ...

Dynamic resource allocation plays a critical role in the next generation of intelligent wireless communication systems. Machine learning has been leveraged as a powerful tool to make strides in this domain. In most cases, the progress has been limited ...

Wireless signal characterization is a growing area of research and an essential tool to enable spectrum monitoring, tactical signal recognition, spectrum management, signal authentication for secure communication, and so on. Recent ...

CSI (Channel State Information) of WiFi systems contains the environment channel response between the transmitter and the receiver, so the people/objects and their movement in between can be sensed. To get CSI, the receiver performs channel estimation ...

Secure ranging is poised to play a critical role in several emerging applications such as self-driving cars, unmanned aerial systems, wireless IoT devices, and augmented reality. In this paper, we propose a design of a secure broadcast ranging system ...

The combination of theory-based and practical hands-on learning represents a powerful approach for cybersecurity education. Placing the student in the adversarial mindset strengthens this approach and is commonly exercised in network penetration testing,...

A new multi-level network combined the Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) is proposed to classify modulation types of signals. The network takes the advantage of CNN in feature extraction and robust to noise and the ...

Internet of Things (IoT) devices have to be small and energy efficient so that resources for security mechanisms tend to be limited. Due to the lack of open source or license free standards, device manufacturers often use proprietary protocols. Software ...

In 4G networks, the emergence of machine communications such as connected vehicles increases the high demand of uplink transmissions, thus, degrading the quality of service per user equipment. Enforcing quality-of-service in such cellular network is ...

We present SparSDR, a resource-efficient architecture for softwaredefined radios whose backhaul bandwidth and compute power requirements scale in inverse proportion to the sparsity (in time and frequency) of the signals received. SparSDR requires ...

Digital forensics is fast-growing field involving the discovery and analysis of digital evidence acquired from electronic devices to assist investigations for law enforcement. Traditional digital forensic investigative approaches are often hampered by ...

Ever increasing bandwidth requirements in satellite communications continuously push the frequency limits. Q‐ band (33 – 50 GHz) is the next frequency band to be populated; however, at these frequencies, the Earth's troposphere (weather) profoundly ...

In order to properly plan radio links, accurate statistical models of radio channels are necessary which are built upon empirical data. Since the Q‐ band lacks such data, we propose a cost‐effective, easy to replicate Q‐ band beacon receiver. We present a ...

Although there is explosive growth of theoretical research on cognitive radio, the real-time platform for cognitive radio is progressing at a low pace. Researchers expect fast prototyping their designs with appropriate wireless platforms to precisely ...

We present an approach for using signal traces from Field Operational Tests (FOTs) for later evaluations and comparative studies of receive algorithms for the IEEE 802.11p PHY. In particular, we use Software Defined Radios (SDRs) to record the raw ...

Reliable network measurements are a fundamental component of networking research as they enable network analysis, system debugging, performance evaluation and optimization. In particular, decoding the LTE control channel would give access to the full ...
