Predictive-State Communication: Innovation Coding and Reconciliation under Delay
Ozgur Ercetin, Mohaned Chraiti
Shannon theory models communication as the reliable transfer of symbol sequences, with performance governed by capacity and rate-distortion limits. When both endpoints possess stro…
On the Structure of the Optimal Detector for Sub-THz Multi-Hop Relays with Unknown Prior: Over-the-Air Diffusion
Ozgur Ercetin, Mohaned Chraiti
Amplify and forward (AF) relaying is a viable strategy to extend the coverage of sub-terahertz (sub-THz) links, but inevitably propagates noise, leading to cumulative degradation a…
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…
Theoretical and Experimental Assessment of Large Beam Codebook at mmWave Devices: How Much is Enough?
Bora Bozkurt, Hasan Atalay Gunel, Mohaned Chraiti +3
Modern millimeter wave (mmWave) transceivers come with a large number of antennas, each of which can support thousands of phase shifter configurations. This capability enables beam…
Beam Codebook Refinement for mmWave Devices with Random Orientations: Concept and Experimental Validation
Bora Bozkurt, Ahmet Muaz Aktas, Hasan Atalay Gunel +3
There is a growing interest in codebook-based beam-steering for millimeter-wave (mmWave) systems due to its potential for low complexity and rapid beam search. A key focus of recen…
