Synchronization Techniques for Digital Receivers PDF Author: Umberto Mengali
Publisher: Springer Science & Business Media
ISBN: 1489918078
Category : Technology & Engineering
Languages : en
Pages : 532

Book Description
Synchronization is a critical function in digital communications; its failures may have catastrophic effects on the transmission system performance. Furthermore, synchronization circuits comprehend such a large part of the receiver hardware that their implementation has a substantial impact on the overall costs. For these reasons design engineers are particularly concerned with the development of new and more efficient synchronization structures. Unfortunately, the advent of digital VLSI technology has radically affected modem design rules, to a point that most analog techniques employed so far have become totally obsolete. Although digital synchronization methods are well established by now in the literature, they only appear in the form of technical papers, often concentrating on specific performance or implementation issues. As a consequence they are hardly useful to give a unified view of an otherwise seemingly heterogeneous field. It is widely recognized that a fundamental understanding of digital synchronization can only be reached by providing the designer with a solid theoretical framework, or else he will not know where to adjust his methods when he attempts to apply them to new situations. The task of the present book is just to develop such a framework.

Book Description
ULTRA WIDEBAND WIRELESS COMMUNICATION AN INTERNATIONAL PANEL OF EXPERTS PROVIDE MAJOR RESEARCH ISSUES AND A SELF-CONTAINED, RAPID INTRODUCTION TO THE THEORY AND APPLICATION OF UWB This book delivers end-to-end coverage of recent advances in both the theory and practical design of ultra wideband (UWB) communication networks. Contributions offer a worldwide perspective on new and emerging applications, including WPAN, sensor and ad hoc networks, wireless telemetry, and telemedicine. The book explores issues related to the physical layer, medium access layer, and networking layer. Following an introductory chapter, the book explores three core areas: Analysis of physical layer and technology issues System design elements, including channel modeling, coexistence, and interference mitigation and control Review of MAC and network layer issues, up to the application Case studies present examples such as network and transceiver design, assisting the reader in understanding the application of theory to real-world tasks. Ultra Wideband Wireless Communication enables technical professionals, graduate students, engineers, scientists, and academic and professional researchers in mobile and wireless communications to become conversant with the latest theory and applications by offering a survey of all important topics in the field. It also serves as an advanced mathematical treatise; however, the book is organized to allow non-technical readers to bypass the mathematical treatments and still gain an excellent understanding of both theory and practice.

Location Fingerprinting for Ultra-wideband Systems

Location Fingerprinting for Ultra-wideband Systems PDF Author: Christoph Steiner
Publisher: Logos Verlag Berlin GmbH
ISBN: 383252567X
Category : Computers
Languages : en
Pages : 177

Book Description
In this thesis, a novel radio frequency based position location concept is proposed and studied, which provides accurate position estimates in dense multipath and non-line-of-sight propagation environments. The main idea is to apply the location fingerprinting paradigm of position location to channel impulse responses with ultra-wide bandwidth. The large bandwidth enables a fine temporal resolution of the multipath propagation channel, which in turn acts as a unique location fingerprint of the positions of transmitter and receiver. At first a location fingerprinting framework is developed from a communication theoretic perspective. Then location fingerprinting with two ultra-wideband receiver structures is studied. The first receiver is able to perform channel estimation and the second receiver is a low complexity generalized energy detection receiver. Their position location performance is analyzed theoretically and experimentally with measured data and it is shown that decimeter accuracy is achievable with both receiver structures in dense multipath and non-line-of-sight propagation environments. However, this experimental performance analysis reveals also a major shortcoming of the proposed method: In order to achieve high position location accuracy, a large amount of training data is required. In order to increase the efficiency of the training phase two promising techniques are proposed in this thesis. The first method is based on the idea of joint localization and training. The second technique is based on a geometrical channel model and utilizes a priori knowledge about the geometry of the propagation environment The thesis concludes with a summary of the major findings and with a list of interesting future research topics in the field of location fingerprinting for ultra-wideband systems.
