In recent years, the protection of communication services operating in the same of adjacent channels has become more and more challenging. Communication systems need to be protected from natural and man-made interference. This practical reference provides a through understanding of how to protect communication systems from intentional and...

Laser space communications is a hot topic among electrical engineers working for the government and in the defense industry, and this groundbreaking resource is the first to offer professionals a thorough, practical treatment of the subject. The book focuses on the feasibility of laser space communications between satellites, satellites and...

Many important GPS applications such as the positioning of wireless devices, tracking during ionospheric scintillation, and orbit determination of geostationary and high Earth orbit satellites require a GNSS (global navigation satellite system) receiver with the ability to work with weak signals. This first-of-its-kind book addresses this...

Role-based access control (RBAC) is a technology that is attracting a great deal of attention, particularly for commercial applications, because of its potential for reducing the complexity and cost of security administration in large networked applications. Under RBAC, security administration is greatly simplified by using roles,...

With its expanding array of applications in everything from biodiversity modeling to wireless communications, it's no wonder digital terrain modeling (DTM) - the electronic process of representing topography in three dimensions -- is a hot subject among engineers and geoscientists. This concise resource is the first truly complete guide...

The continuous developments of software-defined radio technology resulted in the appearance of the first real-time GPS software radios at the beginning of this century. For the first time, it was possible to realize a complete GNSS receiver without going into the depths of cumbersome hardware development that requires development or...

Radio frequency identification (RFID) is gaining in popularity, especially as we find ourselves in this communications age and headed towards a ubiquitous computing world. Automatic identification systems become an important aspect not just in today’s technology but also as part of our daily life. We need RFID in our cars,...

Digital identity can be defined as the digital representation of the information known about a specific individual or organization. Digital identity management technology is an essential function in customizing and enhancing the network user experience, protecting privacy, underpinning accountability in transactions and interactions, and...

Providing a complete introduction to the state-of-the-art in high-speed digital testing with automated test equipment (ATE), this practical resource is the first book to focus exclusively on this increasingly important topic. Featuring clear examples, this one-stop reference covers all critical aspects of the subject, from high-speed digital...

Progress in biology is dependent on the ability to observe, measure, and model the behavior of organisms at multiple levels of abstraction, from the microscopic to the macroscopic. There has been a tremendous growth recently in the techniques to probe the structure and workings of cellular and organ-level mechanisms. Significant advances have...

This book provides an overview of steganography and digital watermarking, two areas of research which are generally referred to as "information hiding." Steganography studies ways to make communication invisible by hiding secrets in innocuous messages, whereas watermarking originated from the need for copyright protection of...
