Economical Caching for Scalable Videos in Cache-enabled Heterogeneous Networks
Xuewei Zhang, Tiejun Lv, Yuan Ren +3
We develop the optimal economical caching schemes in cache-enabled heterogeneous networks, while delivering multimedia video services with personalized viewing qualities to mobile…
Secure Beamforming Design in Relay-Assisted Internet of Things
Pingmu Huang, Yunqin Hao, Tiejun Lv +3
A secure downlink transmission system which is exposed to multiple eavesdroppers and is appropriate for Internet of Things (IoT) applications is considered. A worst case scenario i…
A Belief Propagation Based Framework for Soft Multiple-Symbol Differential Detection
Chanfei Wang, Tiejun Lv, Hui Gao +1
Soft noncoherent detection, which relies on calculating the \textit{a posteriori} probabilities (APPs) of the bits transmitted with no channel estimation, is imperative for achievi…
Distributed User Scheduling for MIMO-Y Channel
Hui Gao, Chau Yuen, Yuan Ren +2
In this paper, distributed user scheduling schemes are proposed for the multi-user MIMO-Y channel, where three -antenna users () are selected from three clust…
An ESPRIT-Based Approach for 2-D Localization of Incoherently Distributed Sources in Massive MIMO Systems
Anzhong Hu, Tiejun Lv, Hui Gao +2
In this paper, an approach of estimating signal parameters via rotational invariance technique (ESPRIT) is proposed for two-dimensional (2-D) localization of incoherently distribut…
A Novel Scheme for Downlink Opportunistic Interference Alignment
Haijing Liu, Hui Gao, Wei Long +1
In this paper we propose a downlink codebook-based opportunistic interference alignment (OIA) in a three-cell MIMO system. A codebook composed of multiple transmit vector sets is u…
