LO-Free Joint Communication and Sensing via Inter-Antenna Cross-Correlation and Graph-Based Spatial Phase Inference
Hasan Atalay Günel, Mohaned Chraiti, Ali Görçin
Joint communication and sensing (JCAS) typically rely on coherent downconversion to recover the phase relationships required for array processing. Meanwhile, Local Oscillators (LOs…
LO-Free Receiver: Next-Gen Low-Power Joint Communication and Sensing
Hasan Atalay Gunel, Mohaned Chraiti, Ali Gorcin
This paper introduces and analyzes Spatial Phase Manifold Communications (SPMC), a paradigm that facilitates joint communication and sensing (JCAS) over Local Oscillator (LO) free…
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…
