Optimal Power Allocation and Active Interference Mitigation for Spatial Multiplexed MIMO Cognitive Systems
Nikolaos I. Miridakis, Minghua Xia, Theodoros A. Tsiftsis
In this paper, the performance of an underlay multiple-input multiple-output (MIMO) cognitive radio system is analytically studied. In particular, the secondary transmitter operate…
Multi-Pair Two-Way Relay Network with Harvest-Then-Transmit Users: Resolving Pairwise Uplink-Downlink Coupling
Shuai Wang, Minghua Xia, Yik-Chung Wu
While two-way relaying is a promising way to enhance the spectral efficiency of wireless networks, the imbalance of relay-user distances may lead to excessive wireless power at the…
Spectral-Efficiency Analysis of Massive MIMO Systems in Centralized and Distributed Schemes
Gervais N. Kamga, Minghua Xia, Sonia Aïssa
This paper analyzes the spectral efficiency of massive multiple-input multiple-output (MIMO) systems in both centralized and distributed configurations, referred to as C-MIMO and D…
Modeling and Analysis of Cooperative Relaying in Spectrum-Sharing Cellular Systems
Minghua Xia, Sonia Aïssa
In this paper, spectrum-sharing technology is integrated into cellular systems to improve spectrum efficiency. Macrocell users are primary users (PUs) while those within local cell…
