Machine-to-Machine (M2M) communications normally require low data transmission rates and low cost devices. Thus, how to modify existing cellular systems such as the Long Term Evolution (LTE) system to successfully support low cost M2M devices will become a major issue for industry. This paper will address one solution based on the virtual carrier system, which […]

Signal Processing Implementation of Virtual Carrier for Supporting M2M Systems Based on LTE
Enabling seamless and mission critical voice and data services is a key requirement for public safety networks during the emergency and natural disaster scenarios. The ability to save lives depends on the reliable and effective communication amongst the first responders and victims. Land Mobile Radio System (LMRS) is a legacy technology which has been used […]
Read moreThis revision specifies technical corrections and clarifications to IEEE Std 802.11 for wireless localarea networks (WLANS) as well as enhancements to the existing medium access control (MAC) and physical layer (PHY) functions. TBD: It also incorporates Amendments 1 and 2 published in 2012.
Read moreThis paper proposes an efficient data compression technique dedicated to implantable intra-cortical neural recording devices. The proposed technique benefits from processing neural signals in the Discrete Haar Wavelet Transform space, a new spike extraction approach, and a novel data framing scheme to telemeter the recorded neural information to the outside world. Based on the proposed […]
Read moreBayesian network classifier (BNCs) are typically implemented on nowadays desktop computers. However, many real world applications require classifier implementation on embedded or low power systems. Aspects for this purpose have not been studied rigorously. We partly close this gap by analyzing reduced precision implementations of BNCs. In detail, we investigate the quantization of the parameters […]

Hierarchical Risk Assessment of Transmission System Considering the Influence of Active Distribution Network
In traditional distribution system, power flow was unidirectional; thus loads were usually aggregated into the substation as an equivalent constant bus in the original risk analysis of transmission system. Detail structures of the distribution system were absolutely ignored. However, distribution system is transformed from passive to active nowadays with more and more distributed generations (DGs) […]
Read moreIn this paper, a general purpose wireless Brain- Machine -Brain Interface (BMBI) system is presented. The system integrates four battery-powered wireless devices for the implementation of a closed-loop sensorimotor neural interface, including a neural signal analyzer, a neural stimulator, a body-areasensor node and a graphic user interface implemented on the PC end. The neural signal analyzer features a four channel […]

A Microwave Imaging-Based Technique to Localize an In-Body RF Source for Biomedical Applications
In some biomedical applications such as wireless capsule endoscopy, the localization of an in-bodyradio-frequency (RF) source is important for the positioning of any abnormality inside the gastrointestinal tract. With knowledge of the location, therapeutic operations can be performed precisely at the position of the abnormality. Electrical properties (relative permittivity and conductivity) of the tissues and […]
Read moreLTE-Advanced has exploited many state of the art technics to identify itself as the main 4G mobile communication system. Among others, Relay station (RS) serves as an important role of LTE-Advanced, which costs much less, consumes less energy, and has the basic function of base station (BS). RS is able to cooperate with BS in system […]
Read moreThe tremendous growth of machine-tomachine (M2M) applications has been a great attractor to cellular network operators to provide machine-type communication services. One of the important challenges for cellular systems supporting M2M terminals is coverage, because terminals can be located in spaces in buildings and structures suffering from significant penetration losses. Since these terminals are also […]
