Zadoff-Chu Sequences for Chirp-Domain Communication: Diversity-Complexity Tradeoffs in Doubly Dispersive Channels
Rawan Alghamdi, Moahmed Siala, Tareq Y. Al-Naffouri +1
Orthogonal frequency-division multiplexing (OFDM) combats multipath-induced time dispersion by dividing the channel into narrowband sub-channels. However, when the channel also exh…
How Many RF Chains Does a Microwave Linear Analog Computer (MiLAC) Need to Match the Fully-Digital Cramér-Rao Bound?
Yuchen Zhang, Yu Ge, Bruno Clerckx +1
A microwave linear analog computer (MiLAC) is a tunable microwave network that performs linear operations directly on radio-frequency signals through wave propagation. Used as an a…
Symbol Error Analysis of Linear Receivers in Terahertz Channels under Channel-Noise Dependence
Almutasem Bellah Enad, Jihad Fahs, Hadi Sarieddeen +2
This paper develops a comprehensive framework for the performance analysis of linear detectors, namely zero-forcing (ZF) and minimum mean-square error (MMSE), under diverse teraher…
Beamforming Design for Stem-Connected Microwave Linear Analog Computer (MiLAC)-Aided Multiuser MISO Downlinks
Yuchen Zhang, Zheyu Wu, Bruno Clerckx +1
A microwave linear analog computer (MiLAC) is a tunable microwave network that leverages wave propagation to perform computation directly in the analog domain. MiLAC finds promisin…
Quadratic Forms in Gaussian Random Variables Theoretical Results and Applications
Mohanad Ahmed, Mahmoud Ghazal, Maaz Mahadi +1
This manuscript reviews theoretical results and applications related to quadratic forms in Gaussian random variables. It summarizes definitions, canonical representations, exact an…
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).…
Handover-Aware Power Minimization for Networked LEO Satellite Communications: Joint Cooperative Beamforming and Scheduling
Yuchen Zhang, Eva Lagunas, Symeon Chatzinotas +1
Networked low Earth orbit (LEO) satellite constellations enabled by inter-satellite links offer a promising path toward ubiquitous broadband non-terrestrial services, as cooperativ…
