Exploiting Mutual Coupling Structure for Channel Estimation of Active RIS-Assisted Links
Simon Tarboush, Pinjun Zheng, Hadi Sarieddeen +2
Accurate channel modeling and estimation of active reconfigurable intelligent surface (RIS)-assisted links with densely integrated elements are essential to fully unleashing this t…
Fast Tri-Hybrid Beamforming via Deep Unfolding
Pinjun Zheng, Md. Jahangir Hossain, Anas Chaaban
Tri-hybrid multiple-input multiple-output architectures have recently emerged as a promising enabler for next-generation wireless systems, as they potentially provide enhanced desi…
Quantization-Aware EE Optimization and SE-EE Tradeoff for MiLAC-Aided MU-MISO Beamforming
Yuchen Zhang, Pinjun Zheng, Tareq Y. Al-Naffouri
In large antenna arrays, hardware power consumption becomes a dominant design constraint, making energy efficiency (EE) a first-class objective alongside spectral efficiency (SE).…
Millimeter-Wave RIS: Hardware Design and System-Level Considerations
Ruiqi Wang, Pinjun Zheng, Yiming Yang +6
Reconfigurable intelligent surfaces have emerged as a promising hardware platform for shaping wireless propagation environments at millimeter-wave (mm-Wave) frequencies and beyond.…
