Butson-type complex Hadamard matrices and association schemes on Galois rings of characteristic 4

Special Matrices, 2018
We consider nonsymmetric hermitian complex Hadamard matrices belonging to the Bose-Mesner algebra of commutative nonsymmetric association schemes. First, we give a characterization of the eigenmatrix of a commutative nonsymmetric association scheme of ...

Joint resource optimization for nonorthogonal multiple access-enhanced scalable video coding multicast in unmanned aerial vehicle-assisted radio-access networks

ETRI Journal, 2023
A joint resource-optimization scheme is investigated for nonorthogonal multiple access (NOMA)-enhanced scalable video coding (SVC) multicast in unmanned aerial vehicle (UAV)-assisted radio-access networks (RANs).

Secure User Association in Two-Tier Heterogeneous Cellular Networks With In-Band Interference

IEEE Access, 2018
In this paper, we address the issue of security-concerned user association in two-tier heterogeneous cellular networks with in-band interference. Different from the maximum secrecy capacity association (max-SC), which studied multi-tier heterogeneous ...

Memory-Based User-Centric Backhaul-Aware User Cell Association Scheme

IEEE Access, 2018
Ultra-dense small cell networks represent a key future network solution that can help meet the exponentially rising traffic requirements of modern wireless networks. Backhauling these small cells are an emerging challenge to the extent that various cells

Public Safety Priority-Based User Association for Load Balancing and Interference Reduction in PS-LTE Systems

IEEE Access, 2016
This paper addresses the issues of user association in multi-tier heterogeneous networks (HetNets) to reduce co-channel interference and provide load balancing for proactively offloading users onto mobile personal cells (mPC).

On association schemes with commutative thin thin residue [PDF]

Transactions on Combinatorics, 2014
The main result of this paper gives a characterization of association schemes having commutative thin thin residue. This gives a generalization of Ito's Theorem on finite groups for association schemes.
