Joint User Association and Pilot Assignment via Phase-Shifted Pilots for Scalable Cell-Free mMIMO
Mumtaz Ozlen, Ahmet Sacid Sumer, Ahmed Naeem +1
Cell-free massive multiple-input multiple-output (CF-mMIMO) promises uniform service across the coverage area, and this service relies on accurate channel estimation for every user…
An HFM-Inspired Random Access Preamble Design for NTN under High Doppler
Mehwish Bibi, Saira Rafique, Ahmed Naeem +1
Non-terrestrial networks (NTNs) are a key enabler of ubiquitous 6G connectivity, but the high orbital velocity and long propagation distances in low-Earth orbit (LEO) NTN operation…
Temporal Broadening-Aware Multiplexing for Joint Sensing and Communication in THz Band
Saira Rafique, Ahmed Naeem, Huseyin Arslan
High-resolution wireless sensing has become an integral component of futuristic 6G networks alongside high-rate communication. Terahertz (THz) band enables both functions through i…
Phase-Shifted Pilot Design for NOMA-Empowered Uplink ISAC Systems
Ahmet Sacid Sümer, Ebubekir Memişoğlu, Hüseyin Arslan
