Artificial Interference Aided Physical Layer Security in Cache-enabled Heterogeneous Networks
Wu Zhao, Zhiyong Chen, Kuikui Li +1
Caching popular contents is a promising way to offload the mobile data traffic in wireless networks, but so far the potential advantage of caching in improving physical layer secur…
Design and Optimization of VoD schemes with Client Caching in Wireless Multicast Networks
Hao Feng, Zhiyong Chen, Hui Liu
Due to the explosive growth in multimedia traffic, the scalability of video-on-demand (VoD) services becomes increasingly important. By exploiting the potential cache ability at th…
Optimal Task Scheduling in Communication-Constrained Mobile Edge Computing Systems for Wireless Virtual Reality
Xiao Yang, Zhiyong Chen, Kuikui Li +2
Mobile edge computing (MEC) is expected to be an effective solution to deliver 360-degree virtual reality (VR) videos over wireless networks. In contrast to previous computation-co…
Signal Shaping for Two-User Gaussian Multiple Access Channels with Computation: Beyond the Cut-Set Bound
Zhiyong Chen, Hui Liu
In this paper, we investigate the signal shaping in a two-user discrete time memoryless Gaussian multiple-access channel (MAC) with computation. It is shown that by optimizing inpu…
