The IEEE 802.15.3 specification is proposed for short-range high-speed Wireless Personal Area Networks (WPANs). Furthermore, it is proposed by the IEEE 802.15.3 a task group for Ultra-Wideband (UWB) transmission, which is an emerging wireless technology for future indoor and outdoor applications. This paper gives a survey on various security aspects and mechanisms in the IEEE 802.15.3 WPANs. It...

In undergoing this life, many people always try to do and get the best. New knowledge, experience, lesson, and everything that can improve the life will be done. However, many people sometimes feel confused to get those things. Feeling the limited of experience and sources to be better is one of the lacks to own. However, there is a very simple thing that can be done. This is what your teacher ...

Ultra wideband radar is one of the most promising techniques for non-invasive imaging in a dielectric medium, which is suitable for both medical screening and non-destructive testing applications. A novel imaging method for such an application is proposed in this brief paper, which has been extended from the advanced range points migration method to a multi-static observation model with circula...
