Edge-Native Environmental Sensing through SDR and TinyML-MEC Framework

Within the 6G paradigm, Integrated Sensing and Communications (ISAC) represents a transformative leap in wireless evolution. As communication networks expand into higher frequency bands (e.g., millimeter-wave and sub-terahertz), signals become vulnerable to dynamic environmental changes. Consequently, environmental sensing becomes critical as it shifts networks from passive data conduits into cognitive infrastructures capable of perceiving physical surroundings, supporting advanced applications like urban digital twins and autonomous vehicular navigation.

The primary challenges of this research lie in extracting environmental monitoring information through light-weight/distributed AI, as well as designing a hybrid AI architecture to intelligently partition and offload complex computational tasks into hardware-constraint platforms. Specifically, the objective is to compress heavy deep learning processes for environmental awareness into ultra-lightweight TinyML modules deployable directly on Software-Defined Radios (SDRs). Seamlessly integrated with Mobile Edge Computing (MEC), this hybridised architecture will enable rapid, low-latency environmental sensing to facilitate the next-gen wireless communication paradigms.

To succeed this project, you will be required to tackle the following/relevant technical bottlenecks:

• Efficiently acquiring and processing complex, high-dimensional environmental sensing data and user physical parameters from both SDR front-ends and complementary sensor networks.
• Architecting hybrid modules to execute high-granularity sensing tasks, e.g. user tracking and identification, dynamic obstacle recognition, and predictive channel estimation, within strict edge resource bounds.
• Robustly decoupling task-specific physical signatures from entangled wireless metrics, including Channel State Information (CSI), amidst severe multipath fading and environmental noises.

Preferred qualifications and hands-on experience include exceptional technical expertise in software-defined radio (SDR), embedded systems, FPGA development, and deployable AI, among other related fields. Candidates with extensive industrial experience are especially welcome to apply.

This project  is open to International students and covers all tuition fees.

Please note that the successful candidate will be responsible for any costs relating to moving to Birmingham and/or visiting the Aston campus. International students must meet the financial requirements for the visa, flights, and NHS Surcharge. Applicants should be confident that they can meet these costs before applying.

Studying a PhD is great route into academia and industries that are centred on research and innovation. Areas with a demand for very high level and specialised research skills often demand PhDs.

In addition to this specialist knowledge, PhD education will help you to develop a set of valuable transferrable skills. The very nature of studying an intensive research degree will enable you to become a team player, develop problem-solving skills, analytical thinking, and advanced presentation and communication skills.

The variety of PhD project topics at Aston means that the destinations of our graduates vary substantially. Some choose to continue into academia, at either Aston or other leading institutions, while others go onto use their newly acquired skills in a range of research, healthcare, industry or charitable fields. When selecting your chosen PhD path at Aston, your supervisor will be able to provide you with relevant career opportunities that could be available to you in your specialist area.
