Optimal Power Allocation for Secure Communications in Large-Scale MIMO Relaying Systems
Jian Chen, Xiaoming Chen, Xiumin Wang +1
In this paper, we address the problem of optimal power allocation at the relay in two-hop secure communications. In order to solve the challenging issue of short-distance intercept…
Statistical Precoder Design for Space-Time-Frequency Block Codes in Multiuser MISO-MC-CDMA Systems
Xiaoming Chen, Xiumin Wang
In this paper, we present a space-time-frequency joint block coding (STFBC) scheme to exploit the essential space-time-frequency degrees of freedom of multiuser MISO-MC-CDMA system…
Coding based Data Broadcasting for Time Critical Applications with Rate Adaptation
Xiumin Wang, Chau Yuen, Yinlong Xu
In this paper, we dynamically select the transmission rate and design wireless network coding to improve the quality of services such as delay for time critical applications. In a…
Energy-Efficient Optimization for Wireless Information and Power Transfer in Large-Scale MIMO Systems Employing Energy Beamforming
Xiaoming Chen, Xiumin Wang, Xianfu Chen
In this letter, we consider a large-scale multiple-input multiple-output (MIMO) system where the receiver should harvest energy from the transmitter by wireless power transfer to s…
Partial Third-Party Information Exchange with Network Coding
Xiumin Wang, Chau Yuen
In this paper, we consider the problem of exchanging channel state information in a wireless network such that a subset of the clients can obtain the complete channel state informa…
Error Correction for Cooperative Data Exchange
Wentu Song, Xiumin Wang, Chau Yuen +2
This paper considers the problem of error correction for a cooperative data exchange (CDE) system, where some clients are compromised or failed and send false messages. Assuming ea…
