Over the past decade, the commercial software-defined radio (SDR) landscape has advanced dramatically—from 6 GHz to 18 GHz maximum frequency, 12 to 16-bit resolution, and 50 MHz to 500 MHz instantaneous bandwidth - the good news is that all of these advancements are available to GNU Radio users. The most transformative shift, however, is the integration of high-performance GPUs, enabling...

Mr Krishna Venkataraman (Flinders University)24/09/2025, 09:30Presentations
For applications involving several RF sensors e.g SDRs (Software Defined Radios,) synchronisation of the RF sources at various nodes, play important role in the mission success. Phase and Time synchronisation among the nodes are specified and measured e.g SSB Phase noise, for a specific goal. This talk will discuss the requirements, measurements and limitations of these parameters briefly.

Radiometric fingerprinting uses unique hardware-induced features in waveforms to identify and profile transmitters. Unlike software-based fingerprints, these features arise from analogue imperfections and serve as reliable markers for device-level authentication. This talk will present recent advances in radiometric fingerprinting, including AI-enabled feature extraction and classification...

Automatic Dependent Surveillance–Broadcast (ADS-B) Mode S messages transmitted at 1090 MHz facilitate aircraft self-reporting telemetry data such as callsign, coordinates, bearing, velocity, and altitude to ground stations. The ADS-B protocol uses a preamble followed by a pulse-position modulated (PPM) data sequence that is simple to demodulate but lacks security features such as encryption,...

A through-the-wall detection (TTW) detection system using opportunistic WiFi signals in real-world environments is of great interest for non-invasive sensing in security, rescue, and monitoring applications. The existing approaches rely on controlled access points or complex MIMO configurations. To address this, in this paper, a TTW detection system that integrates a highly customized...

This paper presents a novel technique for measuring the Allan deviation of the internal oscillator within a software defined radio (SDR). This modified version of the standard double mixer time difference (DMTD) method utilizes the SDR’s analog-to-digital converter (ADC) to eliminate the need for expensive and specialized equipment. By analysing the phase of the sampled signal through the ADC,...
