On the Resilience of Direction-Shift Keying Against Phase Noise and Short Channel Coherence Time at mmWave Frequencies
Mohaned Chraiti, Ozgur Ercetin, Ali Ghrayeb +1
The rapid variation of the wireless channel (short channel coherence time) and the phase noise are two prominent concerns in Millimeter-wave (mmWave) and sub-Terahertz systems comm…
Joint Phase Shift Optimization and Precoder Selection for RIS-Assisted 5G NR MIMO Systems
Osman Mert Yilmaz, Tayfun Yilmaz, Ali Gorcin +3
By intelligently reconfiguring wireless propagation environment, reconfigurable intelligent surfaces (RISs) can enhance signal quality, suppress interference, and improve channel c…
Interference Modulation: A Novel Technique for Low-Rate and Power Efficient Multiple Access
M. Yaser Yagan, Ali E. Pusane, Ali Gorcin +1
The majority of spatial signal processing techniques focus on increasing the total system capacity and providing high data rates for intended user(s). Unlike the existing studies,…
Theoretical and Experimental Assessment of Large Beam Codebook at mmWave Devices: How Much is Enough?
