Convex Optimization Based State Estimation against Sparse Integrity Attacks
Duo Han, Yilin Mo, Lihua Xie
We consider the problem of robust estimation in the presence of integrity attacks. There are m sensors monitoring the state and p of them are under attack. The malicious measuremen…
Mean Square Stabilization of Vector LTI Systems over Power Constrained Lossy Channels
Liang Xu, Yilin Mo, Lihua Xie
This paper studies the mean square stabilization problem of vector LTI systems over power constrained lossy channels. The communication channel is with packet dropouts, additive no…
Distributed Inference for Relay-Assisted Sensor Networks With Intermittent Measurements Over Fading Channels
Shanying Zhu, Yeng Chai Soh, Lihua Xie
In this paper, we consider a general distributed estimation problem in relay-assisted sensor networks by taking into account time-varying asymmetric communications, fading channels…
Mean Square Capacity of Power Constrained Fading Channels with Causal Encoders and Decoders
Liang Xu, Lihua Xie, Nan Xiao
This paper is concerned with the mean square stabilization problem of discrete-time LTI systems over a power constrained fading channel. Different from existing research works, the…
Vandermonde Decomposition of Multilevel Toeplitz Matrices with Application to Multidimensional Super-Resolution
Zai Yang, Lihua Xie, Petre Stoica
The Vandermonde decomposition of Toeplitz matrices, discovered by Carathéodory and Fejér in the 1910s and rediscovered by Pisarenko in the 1970s, forms the basis of modern subspace…
An Improved Stability Condition for Kalman Filtering with Bounded Markovian Packet Losses
Junfeng Wu, Ling Shi, Lihua Xie +1
In this paper, we consider the peak-covariance stability of Kalman filtering subject to packet losses. The length of consecutive packet losses is governed by a time-homogeneous fin…
