Time-triggered Ethernet (TTE) has its unique TT traffic schedule to guarantee a global communication scheme. Scheduling problem in TTE's static segment is regarded as NP complete problem for its mess constrains, complex topology and large scale of messages. Another problem in TT traffic scheduling is lack of flexibility. Former scheduled communication table is unable to be compatible with extended...
This paper presents a new architecture of super regenerative On-Off keying receiver (SROOK RX) applying to the 5.8GHz Industrial Scientific Medical (ISM) band in TSMC 0.18 μm process. The proposed SROOK Rx uses a quenched oscillator to reduce the required gain of Low Noise Amplifier (LNA) and can achieve low power consumption. The technology of pulse width demodulator employs the Pulse-Width Expander...
Cellular network assisted device-to-device (D2D) communication relies on efficient resource sharing strategies between cellular users (CUs) and D2D users. This paper investigates uplink resource sharing between multiple D2D links and CUs. Upon guaranteeing the quality of normal cellular communication, we try to explore the full benefit of D2D communication by allowing multiple D2D links to share the...
Eigenvalue-based detectors are considered as an important method of spectrum sensing since they do not require the information about the Primary User (PU)signal. In this paper we propose a method to improve the performance of the eigenvalue-based detector. In the proposed method, covariance matrix is calculated by a combinatorial matrix whose components are overlapping subgroups extracted from the...
Fatigue is a complex physiological phenomena which is a kind of human body's natural response and self-regulation for protection. Detection of fatigue is becoming indispensable for its positive significance in scientific physical training. Recently, many researchers from both speech signal area and machine learning area have already shown that automatically fatigue detection from speech can carry...
Traditional parameters estimation methods for the Multi-component Linear Frequency Modulation (MLFM) signal based on Fractional Fourier Transform (FRFT) could not achieve the satisfactory precision and the lesser computation cost. In this paper, we propose a new method combining the Short Time Fourier Transform (STFT) and Zoom-FRFT, to estimate the MLFM signal parameters. Firstly, the coarse estimation...
The brain tumor segmentation method of MRI images is of key importance for clinical analysis of glioma. The majority of existing methods are focused on structural MRI such as T1-weighted and T2-weighted. Additionally, functional MRI including Magnetic Resonance Spectroscopy (MRS), Diffusion Weighted Imaging (DWI), and Blood-Oxygen-Level Dependent (BOLD) can also contribute to increasing the validity...
In this paper, we present an approach to classify Chinese digital gesture based on convolutional neural network (CNN). Principal Component Analysis (PCA) is employed to learn convolution kernels as the pre-training strategy. The learned convolution kernels are used for extracting features instead of the random convolution kernels. The convolutional layers can be directly implemented without any further...
Diabetes occurs when the pancreas fails to secrete enough insulin, slowly affecting the retina of the human eye, leading to diabetic retinopathy. The blood vessels in the retina get altered and have abnormality. Exudates are secreted, micro-aneurysms and haemorrhages occur in the retina. The appearance of these features represents the degree of severity of the disease. Early detection of diabetic...

In this study, we develop a wearable device which uses a novel strategy for Automatic Activity Recognition (AAR) system. This new system will not only reduce power consumption, but also improve the accuracy and stability of the system. This system will be linked with wireless network (Bluetooth) and passing the data processed by the AAR system from the device to smartphone. The novel strategy for...
The migration of virtual router has attracted a lot of attention from researchers in the new network architecture field, due to the potential to cope with emerging challenges, such as energy consumption and resource fragmentation problem. In this paper, we focus on general virtual router architecture VRSM (Virtual Router Supporting Migration), composed by a cluster of servers. Compared with other...
High performance spatial signal processing relies on accurate beam-forming. In a practical antenna system, due to inevitable aging and heat distortion of the components, there exists an inconsistency between the designed Beam-forming Network (BFN) Weighted Matrix (WM) and the actual value of it. However, the complexity of BFN WM measurement is in direct ratio to the channel numbers of BFN. For large-scale...
Indoor positioning has been getting more attention of researchers for academic as well as industrial point of view. However, because the propagation of Wi-Fi signals is greatly affected by the serious NLOS (non-line-of sight) effect for indoor environment. Therefore, the accuracy measure is deteriorated due to random NLOS effect in indoor wireless communication. In this paper, we propose a localization...
Along with the development of semiconductor's channel length that narrows toward the deep submicron and even nanometer, the design of SoC has become increasingly complex. Therefore, how to achieve fault tolerance, aiming to avoid the impact process issues and improve reliability of system, has become the focus of the NoC design. This paper presents a fault tolerance routing method on NoC system that...
The requirement of high data rate and energy efficiency for a new generation of wireless network should reshape the designs of wireless heterogeneous network architecture including wireless relaying. For two-top bi-directional information exchange in wireless networks, we consider a wireless transmission design, which adopts the bi-directional relaying channel and the physical broadcasting.

Attacks in network have caused a variety of serious problems, but intrusion detection in network is still an immature technology. And it is very important for network security to timely detect anomalies and rapidly response. Many intrusion detection methods have been proposed from simple to sophisticated techniques in the literature. Among them, the Context-Based Intrusion Detection (CBID) algorithm...
