Space-Time Hierarchical-Graph Based Cooperative Localization in Wireless Sensor Networks
Tiejun Lv, Hui Gao, Xiaopeng Li +2
It has been shown that cooperative localization is capable of improving both the positioning accuracy and coverage in scenarios where the global positioning system (GPS) has a poor…
Phase-Rotation-Aided Relay Selection in Two-Way Decode-and-Forward Relay Networks
Ruohan Cao, Hui Gao, Tiejun Lv +2
This paper proposes a relay selection scheme that aims to improve the end-to-end symbol error rate (SER) performance of a two-way relay network (TWRN). The TWRN consists of two sin…
Joint Multiple Symbol Differential Detection and Channel Decoding for Noncoherent UWB Impulse Radio by Belief Propagation
Taotao Wang, Tiejun Lv, Hui Gao +1
This paper proposes a belief propagation (BP) message passing algorithm based joint multiple symbol differential detection (MSDD) and channel decoding scheme for noncoherent differ…
Low-Complexity Downlink User Selection for Massive MIMO Systems
Haijing Liu, Hui Gao, Shaoshi Yang +1
In this paper we propose a pair of low-complexity user selection schemes with zero-forcing precoding for multiuser massive MIMO downlink systems, in which the base station is equip…
Secrecy Transmit Beamforming for Heterogeneous Networks
Tiejun Lv, Hui Gao, Shaoshi Yang
In this paper, we pioneer the study of physical-layer security in heterogeneous networks (HetNets). We investigate secure communications in a two-tier downlink HetNet, which compri…
