This paper is concerned with the reliable H∞ filtering problem for a class of stochastic spatial-temporal systems with sensor saturations and failures. Different from the continuous-spatial temporal systems, the dynamic behaviour of the system under consideration evolves in a discrete rectangular region. The aim of this paper is to estimate the system(More)
This paper studies a Quantized Gossip-based Interactive Kalman Filtering (QGIKF) algorithm implemented in a wireless sensor network, where the sensors exchange their quantized states with neighbors via inter-sensor communications. We show that, in the countable infinite quantization alphabet case, the network can still achieve weak consensus with the(More)
In this paper, the robust state estimation problem is investigated for the complex-valued neural networks involving parameter uncertainties, mixed time delays, as well as stochastic disturbances by resorting to the sampled-data information from the available output measurements. The parameter uncertainties are assumed to be norm-bounded and the stochastic(More)
This paper is concerned with the robust reliable H∞ output-feedback control problem for a class of uncertain spatialtemporal systems. The system under consideration resides in a given discrete rectangular region and its states evolve not only over time but also over space. A set of sensors located at the specified points is used to measure the system(More)
An investigation of the electrocardiogram (ECG) signals and arrhythmia characterization by wavelet energy is proposed. This study employs a wavelet based feature extraction method for congestive heart failure (CHF) obtained from the percentage energy (PE) of terminal wavelet packet transform (WPT) subsignals. In addition, the average framing percentage(More)
The selection of a suitable representing model for 3D laser point clouds plays a significant role in 3D outdoor scene understanding. In this paper, we compare the segmentation performance of four types of models which can transform 3D laser point clouds into 2D images. In these models, fast optimal bearing-angle (FOBA) image is a novel 2D image model, which(More)
The heterogeneous system, where small networks (e.g., femtocell or WiFi) boost the system capacity under the umbrella of a large network (e.g., cellular systems), is a promising architecture for the next generation wireless communication systems. In addition, energy harvesting (EH) based green communication is one key next-generation technology. In this(More)
A heterogeneous system, where small networks (e.g., small cell or WiFi) boost the system throughput under the umbrella of a large network (e.g., large cell), is a promising architecture for the 5G wireless communication networks, where green and sustainable communication is also a key aspect. Renewable energy based communication via energy harvesting (EH)(More)
This paper is concerned with the fault detection filter design problem for uncertain linear discrete-time system in finite-frequency domain with regional pole assignment. An optimized fault detection filter is designed such that 1) the fault detection dynamics is quadratically D-stable; 2) the effect from the exogenous disturbance on the residual is(More)
