Your role

As a PhD candidate, you will conduct advanced research on the physical-layer integration of communication and positioning in next-generation 5G/6G Non-Terrestrial Networks (NTNs), with a focus on LEO satellite systems.

Your responsibilities will include:

• Investigating joint communication and positioning techniques at the waveform and receiver levels, including integrated signal design and synchronization strategies
• Developing signal processing and estimation algorithms for positioning in high-dynamics NTN scenarios, accounting for satellite mobility, Doppler effects, and time-varying propagation conditions
• Exploring GNSS-5G coexistence and hybrid positioning approaches for resilient PNT in degraded and interference-prone
• Aligning the research with ongoing 3GPP developments in 5G/6G NTN and positioning standardization
• Publishing results in leading peer-reviewed journals and presenting at major international conferences
