Evan Allen, Karim Said, Robert Calderbank +1
As 6G technologies advance, international bodies and regulatory agencies are intensifying efforts to extend seamless connectivity especially for high-mobility scenarios such as Mob…
Spreading over OFDM for Integrated Sensing and Communications (ISAC) Ranging: Multi-user Interference Mitigation
Karim A. Said, Ibraheem Alturki, Husheng Li +2
In the context of communication-centric integrated sensing and communication (ISAC), the orthogonal frequency division multiplexing (OFDM) waveform was proven to be optimal in mini…
Mobile Distributed MIMO (MD-MIMO) for NextG: Mobility Meets Cooperation in Distributed Arrays
Karim A. Said, Yibin Liang, Usama Saeed +13
Distributed multiple-input multiple-output (D\mbox{-}MIMO) is a promising technology to realize the promise of massive MIMO gains by fiber-connecting the distributed antenna arrays…
Reducing Inter-user Interference: Precoding over OFDM for Enhanced MTC
Karim A. Said, A. A. Louis Beex, Elizabeth Bentley +1
In the physical layer (PHY) of modern cellular systems, information is transmitted as a sequence of resource blocks (RBs) across various domains with each resource block limited to…
