The concept of medical treatment from a distance (in absentia care) is actually quite ancient, dating back to tribal days where smoke signals were used to warn of serious disease in a community. Nowadays, telemedicine is used to facilitate treatment in rural areas, where the nearest doctor is miles away, through various forms of information technology, including videoconferencing and digital imaging. It can also be used to conveniently monitor chronically ill patients through electronic devices so that they can enjoy a better quality of life. But despite the strides that have been made...

It's always great to see people's faces when they copy their first Flash Lite applications or games onto their phones and press Run. The reaction is usually, "Wow " Even something that would appear trivial when viewed on a web site somehow looks wholly impressive when running on that little color screen in your hand. By picking up this book, you're guaranteed to experience this moment for yourself. The aims of this book are to build on your current skill level--whether you're a beginner with no experience with Flash or an advanced coder with years of web programming prowess--and to give you...

Optimization of adaptive signal processing algorithms for wireless communications is based on a model of the underlying propagation channel. In practice, this model is never known perfectly. For example, its parameters have to be estimated and are only known with significant errors.

In this book, a systematic treatment of this practical design problem is provided for signal processing in the physical layer with multiple antennas. The design of robust signal processing algorithms is based on a description of the errors and the uncertainties in the system's model. It applies...

Helps you understand the dimensions of WiMAX and integration of communication, broadcasting and Multimedia technologies. This book outlines migrating to a generation of broadcasting which integrates the Mobile, Wireless and Fixed network domains. It covers mobile broadcasting using a WiMAX network.

Intra-system EMC problems are becoming increasingly common in mobile devices, ranging from notebook PCs to cell phones, with RF/wireless capbilities. These issues range from minor annoyances to serious glitches which impede the functioning of the device. This book gives a thourough review of electromagnetic theory (including Maxwell's equations), discusses possible sources and causes of intra-system interference, shows to use models and analysis to discover potential sources of intra-system EMC in a design, how to use appropriate tests and measurements to detect intra-system EMC problems, and...

"Cuts through the hype Golding's compelling offers visionary, but practical insights. A "must have" reference treatment for all practitioners in the mobile innovation space."
