On The Classification-Distortion-Perception Tradeoff
Dong Liu, Haochen Zhang, Zhiwei Xiong
Signal degradation is ubiquitous and computational restoration of degraded signal has been investigated for many years. Recently, it is reported that the capability of signal resto…
When Exploiting Individual User Preference Is Beneficial for Caching at Base Stations
Dong Liu, Chenyang Yang, Victor C. M. Leung
Most of prior works optimize caching policies based on the following assumptions: 1) every user initiates request according to content popularity, 2) all users are with the same ac…
Optimal Content Placement for Offloading in Cache-enabled Heterogeneous Wireless Networks
Dong Liu, Chenyang Yang
Caching at base stations (BSs) is a promising way to offload traffic and eliminate backhaul bottleneck in heterogeneous networks (HetNets). In this paper, we investigate the optima…
Cache-enabled Heterogeneous Cellular Networks: Comparison and Tradeoffs
Dong Liu, Chenyang Yang
Caching popular contents at base stations (BSs) is a promising way to unleash the potential of cellular heterogeneous networks (HetNets), where backhaul has become a bottleneck. In…
