WiMax Operators Manual : Building 802.16 Wireless Networks
Includes most of the material from the first edition, plus new discussions about the ultra-fast mobile telephone standard High Speed Downlink Packet Access (HSDPA) and the Ultra Wideband (UWB) technology. Other topics include mobile voice and entertainment, new backup systems, and changes to DSL technologies. The book addresses the planning, construction, and day-to-day operation of a standards-based broadband wireless network. It examines the advantages of broadband wireless and how it constitutes an ideal solution. It also explains the unique difficulties, challenges, and limitations of broadband wireless. This book illustrates how to plan and run networks, and indicates which specialized services should be secured. You’ll learn how to plan a successful, profitable broadband wireless network in a short amount of time.
Wideband Low Noise Amplifiers Exploiting Thermal Noise Cancellation
This book is directly relevant for IC designers and researchers working on integrated transceivers. Although the focus is on CMOS circuits, the techniques can just as well be applied to other IC technologies, e.g. bipolar and GaAs, and even in discrete component technologies. Low Noise Amplifiers (LNAs) are commonly used to amplify signals that are too weak for direct processing for example in radio or cable receivers. Traditionally, low noise amplifiers are implemented via tuned amplifiers, exploiting inductors and capacitors in resonating LC-circuits. This can render very low noise but only in a relatively narrow frequency band close to resonance. There is a clear trend to use more bandwidth for communication, both via cables (e.g. cable TV, internet) and wireless links (e.g. satellite links and Ultra Wideband Band).
Ultra Wideband - Circuits, Transceivers and Systems : Circuits, Transceivers and Systems
Ultra Wideband: Circuits, Transceivers and Systems offers a comprehensive overview of the state of the art of the physical implementation of Ultra Wideband transceivers. It addresses system level aspects, architectural design issues, circuit level implementation challenges as well as emerging challenges in the field.The topics covered include an overview of circuit techniques for broadband applications which provides a comparative analysis of various broadband implementations for different parts of the transceiver such as amplifiers, oscillators and filters. The book also includes system proposals for Ultra Wideband which gives a historical perspective of the development of Ultra Wideband,
Silicon-Based RF Front-Ends for Ultra Wideband Radios
The book begins with an introduction of several transceiver architectures for UWB. The discussion then focuses on RF front-end of the UWB radio. First, the design and analysis of a performance-optimized CMOS distributed LNA is presented. This is followed by design of novel distributed RF front-ends for UWB IF-receivers (UWB-DRF). The book continues with the introduction of a novel distributed direct conversion RF front-end (DDC-RF). The DDC-RF power and area-efficiently combines the wideband distributed approach with IQ requirement of a direct conversion receiver. Furthermore, deploying merged LNA/mixer enables low-power design, while achieving superior linearity over the conventional distributed amplifiers.
