Outage Constrained Robust Transmit Optimization for Multiuser MISO Downlinks: Tractable Approximations by Conic Optimization
Kun-Yu Wang, Anthony Man-Cho So, Tsung-Hui Chang +2
In this paper we consider a probabilistic signal-to-interference and-noise ratio (SINR) constrained problem for transmit beamforming design in the presence of imperfect channel sta…
Coordinated Beamforming for Multiuser MISO Interference Channel under Rate Outage Constraints
Wei-Chiang Li, Tsung-Hui Chang, Che Lin +1
This paper studies the coordinated beamforming design problem for the multiple-input single-output (MISO) interference channel, assuming only channel distribution information (CDI)…
Distributed Robust Multi-Cell Coordinated Beamforming with Imperfect CSI: An ADMM Approach
Chao Shen, Tsung-Hui Chang, Kun-Yu Wang +2
Multi-cell coordinated beamforming (MCBF), where multiple base stations (BSs) collaborate with each other in the beamforming design for mitigating the inter-cell interference, has…
Worst-Case SINR Constrained Robust Coordinated Beamforming for Multicell Wireless Systems
Chao Shen, Kun-Yu Wang, Tsung-Hui Chang +2
Multicell coordinated beamforming (MCBF) has been recognized as a promising approach to enhancing the system throughput and spectrum efficiency of wireless cellular systems. In con…
Optimal Real-time Spectrum Sharing between Cooperative Relay and Ad-hoc Networks
Yin Sun, Xiaofeng Zhong, Tsung-Hui Chang +3
Optimization based spectrum sharing strategies have been widely studied. However, these strategies usually require a great amount of real-time computation and significant signaling…
