Cell-Edge Detection via Selective Cooperation and Generalized Canonical Correlation
Mohamed Salah Ibrahim, Ahmed S. Zamzam, Aritra Konar +1
Improving the uplink quality of service for users located around the boundaries between cells is a key challenge in LTE systems. Relying on power control, existing approaches throt…
Reliable Detection of Unknown Cell-Edge Users Via Canonical Correlation Analysis
Mohamed Salah Ibrahim, Nicholas D. Sidiropoulos
Providing reliable service to users close to the edge between cells remains a challenge in cellular systems, even as 5G deployment is around the corner. These users are subject to…
Fast Algorithms for Joint Multicast Beamforming and Antenna Selection in Massive MIMO
Mohamed Salah Ibrahim, Aritra Konar, Nicholas D. Sidiropoulos
Massive MIMO is currently a leading physical layer technology candidate that can dramatically enhance throughput in 5G systems, for both unicast and multicast transmission modaliti…
Amplitude Retrieval for Channel Estimation of MIMO Systems with One-Bit ADCs
Cheng Qian, Xiao Fu, Nicholas D. Sidiropoulos
This letter revisits the channel estimation problem for MIMO systems with one-bit analog-to-digital converters (ADCs) through a novel algorithm--Amplitude Retrieval (AR). Unlike th…
Algebraic Channel Estimation Algorithms for FDD Massive MIMO systems
Cheng Qian, Xiao Fu, Nicholas D. Sidiropoulos
We consider downlink (DL) channel estimation for frequency division duplex based massive MIMO systems under the multipath model. Our goal is to provide fast and accurate channel es…
Data-Driven Learning-Based Optimization for Distribution System State Estimation
Ahmed S. Zamzam, Xiao Fu, Nicholas D. Sidiropoulos
Distribution system state estimation (DSSE) is a core task for monitoring and control of distribution networks. Widely used algorithms such as Gauss-Netwon perform poorly with the…
