Joint Beam Routing and Resource Allocation Optimization for Multi-IRS-Reflection Wireless Power Transfer
Weidong Mei, Zhi Chen, Rui Zhang
Intelligent reflecting surface (IRS) can be densely deployed in complex environments to create cascaded line-of-sight (LoS) links between base stations (BSs) and users, which signi…
Deep Global-Connected Net With The Generalized Multi-Piecewise ReLU Activation in Deep Learning
Zhi Chen, Pin-han Ho
Recent Progress has shown that exploitation of hidden layer neurons in convolution neural networks incorporating with a carefully designed activation function can yield better clas…
Optimal Power Control for Transmitting Correlated Sources with Energy Harvesting Constraints
Yunquan Dong, Zhi Chen, Jian Wang +1
We investigate the weighted-sum distortion minimization problem in transmitting two correlated Gaussian sources over Gaussian channels using two energy harvesting nodes. To this en…
Joint Power Minimization Over Multi-Carrier Two-Way Relay Networks
Zhi Chen, Pin-Han Ho, Li Mei Peng
The study considers a three-node, two-way relaying network (TWRN) over a multi-carrier system, aiming to minimize the total power consumption of all the transmit and receiver activ…
QoS Guaranteed Energy Minimization Over Two-Way Relaying Networks
Zhi Chen, Pin-Han Ho
In this work, we consider a typical three-node, two-way relaying network (TWRN) over fading channels. The aim is to minimize the entire system energy usage for a TWRN in the long r…
Weighted Sum-Throughput Maximization for MIMO Broadcast Channel: Energy Harvesting Under System Imperfection
Zhi Chen, Pingyi Fan, Dapeng Oliver Wu +1
In this work, a MIMO broadcast channel under the energy harvesting (EH) constraint and the peak power constraint is investigated. The transmitter is equipped with a hybrid energy s…
Mobility-Aware Uplink Interference Model for 5G Heterogeneous Networks
Yunquan Dong, Zhi Chen, Pingyi Fan +1
To meet the surging demand for throughput, 5G cellular networks need to be more heterogeneous and much denser, by deploying more and more small cells. In particular, the number of…
Fading Two-Way Relay Channels: Physical-Layer Versus Digital Network Coding
Zhi Chen, Tengjoon Lim, Mehul Motani
In this paper, we consider three transmit strategies for the fading three-node, two-way relay network (TWRN) -- physical-layer network coding (PNC), digital network coding (DNC) an…
Throughput Optimized Multi-Source Cooperative Networks With Compute-and-Forward
Z. Chen, P. Fan, K. B. Letaief
In this work, we investigate a multi-source multi-cast network with the aid of an arbitrary number of relays, where it is assumed that no direct link is available at each S-D pair.…
Digital Network Coding Aided Two-way Relaying: Energy Minimization and Queue Analysis
Zhi Chen, Teng Joon Lim, Mehul Motani
In this paper, we consider a three node, two-way relay system with digital network coding over static channels where all link gains are assumed to be constant during transmission.…
