QoS-Based Source and Relay Secure Optimization Design with Presence of Channel Uncertainty
Meng Zhang, Jian Huang, Hui Yu +2
In this letter, we study relay-aided networks with presence of single eavesdropper. We provide joint beamforming design of the source and relay that can minimize the overall power…
Robust Beamforming Design for Sum Secrecy Rate Optimization in MU-MISO Networks
Pu Zhao, Meng Zhang, Hui Yu +2
This paper studies the beamforming design problem of a multi-user downlink network, assuming imperfect channel state information known to the base station. In this scenario, the ba…
MMSE Based Greedy Antenna Selection Scheme for AF MIMO Relay Systems
Ming Ding, Shi Liu, Hanwen Luo +1
We propose a greedy minimum mean squared error (MMSE)-based antenna selection algorithm for amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay systems. Assuming e…
Leakage-Based Robust Beamforming for Multi-Antenna Broadcast System with Per-Antenna Power Constraints and Quantized CDI
Ming Ding, Meng Zhang, Hanwen Luo +1
In this paper, we investigate the robust beamforming schemes for a multi-user multiple-input-single-output (MU-MISO) system with per-antenna power constraints and quantized channel…
Sequential and Incremental Precoder Design for Joint Transmission Network MIMO Systems with Imperfect Backhaul
Ming Ding, Jun Zou, Zeng Yang +2
In this paper, we propose a sequential and incremental precoder design for downlink joint transmission (JT) network MIMO systems with imperfect backhaul links. The objective of our…
