Robustly Stable Signal Recovery in Compressed Sensing with Structured Matrix Perturbation
Zai Yang, Cishen Zhang, Lihua Xie
The sparse signal recovery in the standard compressed sensing (CS) problem requires that the sensing matrix be known a priori. Such an ideal assumption may not be met in practical…
On Phase Transition of Compressed Sensing in the Complex Domain
Zai Yang, Cishen Zhang, Lihua Xie
The phase transition is a performance measure of the sparsity-undersampling tradeoff in compressed sensing (CS). This letter reports our first observation and evaluation of an empi…
Distributed Consensus of Linear Multi-Agent Systems with Adaptive Dynamic Protocols
Zhongkui Li, Xiangdong Liu, Wei Ren +1
This paper considers the distributed consensus problem of multi-agent systems with general continuous-time linear dynamics. Two distributed adaptive dynamic consensus protocols are…
Distributed Robust Control of Linear Multi-Agent Systems with Parameter Uncertainties
Zhongkui Li, Zhisheng Duan, Lihua Xie +1
This paper considers the distributed robust control problems of uncertain linear multi-agent systems with undirected communication topologies. It is assumed that the agents have id…
Off-grid Direction of Arrival Estimation Using Sparse Bayesian Inference
Zai Yang, Lihua Xie, Cishen Zhang
Direction of arrival (DOA) estimation is a classical problem in signal processing with many practical applications. Its research has recently been advanced owing to the development…
