Machine Learning-Based Antenna Selection in Untrusted Relay Networks
Rugui Yao, Yuxin Zhang, Nan Qi +1
This paper studies the transmit antenna selection based on machine learning (ML) schemes in untrusted relay networks. First, we state the conventional antenna selection scheme. The…
Effective Capacity for Renewal Service Processes with Applications to HARQ Systems
Zheng Shi, Theodoros Tsiftsis, Weiqiang Tan +3
Considering the widespread use of effective capacity in cross-layer design and the extensive existence of renewal service processes in communication networks, this paper thoroughly…
Base Station Cooperation in Millimeter Wave Cellular Networks: Performance Enhancement of Cell-Edge Users
Hui-Ming Wang, Ke-Wen Huang, Theodoros A. Tsiftsis
Millimeter wave (mmWave) signals are much more sensitive to blockage, which results in a significant increase of the outage probability, especially for the users at the edge of the…
Cooperative Secure Transmission by Exploiting Social Ties in Random Networks
H. -M. Wang, Y. Xu, K. -W. Huang +2
Social awareness and social ties are becoming increasingly popular with emerging mobile and handheld devices. Social trust degree describing the strength of the social ties has dra…
A New Interweave Cognitive Radio Scheme for Out-band Energy Harvesting Systems
Nikolaos I. Miridakis, Theodoros A. Tsiftsis
In this paper, a new interweave cognitive radio (CR) transmission scheme is analytically presented for energy harvesting (EH)-enabled transmitting nodes. EH is performed via a dedi…
MIMO Underlay Cognitive Radio: Optimized Power Allocation, Effective Number of Transmit Antennas and Harvest-Transmit Tradeoff
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, George C. Alexandropoulos
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…
Multiple Antennas Secure Transmission under Pilot Spoofing and Jamming Attack
Hui-Ming Wang, Ke-Wen Huang, Theodoros A. Tsiftsis
Transmitter-side channel state information (CSI) of the legitimate destination plays a critical role in physical layer secure transmissions. However, channel training procedure is…
