Stacked intelligent metasurface (SIM) can perform signal processing in the wave domain by intelligently optimizing the phase shifts of transmissive meta-elements on each layer. However, it typically requires high overhead to acquire channel state information. In this letter, we propose a hierarchical codebook design fo...

The constructive interference (CI)-based block-level precoding (CI-BLP) approach reduces computational complexity compared to conventional CI-based symbol-level precoding (CI-SLP) and provides additional design flexibility due to its relaxed block-level design. However, using a constant precoding matrix within each blo...

The coexistence between terrestrial 5G networks and low Earth orbit (LEO) satellite systems in the C-band has raised increasing concerns due to the aggregated impact of out-of-band emissions (OOBE) from active antenna systems (AAS). This paper investigates the interference generated by terrestrial 5G downlink transmiss...

Inter-satellite links (ISLs) are essential to the evolution of next-generation satellite constellations, providing the foundation for low-latency, resilient, and globally scalable connectivity. While low radio-frequency (RF)-based ISLs offer technological maturity, they are increasingly constrained by spectrum scarcity...

Future multi-satellite networks can enhance downlink reliability through cooperative reception at geographically distributed ground nodes (GNs), but limited fronthaul restricts centralized signal collection and instantaneous channel state information (CSI) exchange. We develop distributed beamforming where GNs combine...

This paper investigates polarization-aware transmission for multi-user multiple-input single-output (MU-MISO) short-packet ultra-reliable low-latency communications (URLLC) under imperfect channel state information (CSI). We consider a system in which the base station (BS) and users are equipped with polarization-recon...
This survey provides an infrastructure-oriented review of QKD networks, examining architectural models, quantum randomness as a root of trust, FPGA and system-on-chip (SoC) based acceleration techniques, and programmable control-plane integration.

We develop a quantum-decision-theoretic framework for detecting phase-space displacements with finite-energy, $d$-level Gottesman-Kitaev-Preskill (GKP) probes. For single-mode and entanglement-assisted architectures, we derive the Bayesian minimum-error probability, the optimal Neyman-Pearson receiver-operating charact...
A selective handover strategy is proposed where the path recomputation and VNF remapping are done only if there is a change in the previous routing path, which ensures that only critical handovers are carried out while discouraging unnecessary reconfigurations, which result in service discontinuity.

A common system model is developed that connects QRC foundations, computational properties, reservoir architectures, operating protocols, and physical implementations and specifies the resource accounting, benchmark standards, and theoretical criteria needed to evaluate claims of quantum advantage.
