The radio-frequency environment has an obvious and direct influence on the performance of electronic systems that depend upon the transfer of energy through space for their operation. Examples of such systems include radio communications, radio navigation, radar, and commercial AM, FM, and television broadcast systems. Less obvious, but nonetheless significant, is the influence the radio-frequency environment can have on electronic systems that ostensibly do not depend on the transfer of energy through space, for example, the degradation caused by electromagnetic fields generated by citizens band radios, radars, lightning, power lines, and electrostatic discharges on the performance of computers, process control equipments, automotive elec tronics and biomedical instrumentation. The beneficial and deleterious effects of man-made and naturally occurring electromagnetic fields on biological systems, including human beings, although little understood at present, may have more important long-term consequences than upon in the operation of equipment. As the radio-frequency environment evolves with the progression of the electronic age, the necessity to monitor, measure, and characterize it assumes greater importance. The purpose of this book is to provide, in a single self contained volume, the necessary background and methodology needed to execute a survey of the RF environment. We have included representative data on natural and man-made ambients in a variety of settings, wave propagation fundamentals, instrumentation descriptions, survey procedures, and data ana lysis techniques. Much experimental effort has been expended during this century to es tablish an adequate body of knowledge on the radio-frequency environment.

Get to grips with the principles and practice of signal processing used in mobile communications systems. Focusing particularly on speech, video, and modem signal processing, pioneering experts employ a detailed, top-down analytical approach to outline the network architectures and protocol structures of multiple generations of mobile communications systems, identify the logical ranges where media and radio signal processing occur, and analyze the procedures for capturing, compressing, transmitting, and presenting media. Chapters are uniquely structured to show the evolution of network architectures and technical elements between generations up to and including 5G, with an emphasis on maximizing service quality and network capacity through re-using existing infrastructure and technologies. Implementation examples and data taken from commercial networks provide an in-depth insight into the operation of real mobile communications systems, including GSM, cdma2000, W-CDMA, LTE, and LTE-A, making this a practical, hands-on guide for both practicing engineers and graduate students in wireless communications.

A MATLAB(r)-based FM demodulator for the RBDS system was designed to investigate software-based FM demodulator techniques. An overview of the operation of FM decoder design is presented. The FM radio signal contains stereo/audio, as well as RBDS data. This book develops a design for FM radio receiver that extracts these message elements from the RBDS data and displays the message details in a user-friendly format. Agilent vector signal analyzer (VSA-89600) is used to capture radio signals from a local radio station, and to convert this received FM radio signal into a MATLAB(r)-compatible format. The signal is then recorded on the host computer and processed using signal processing algorithms. Derivations and designs are done for various blocks of the processing chain to extract the RBDS signal from the FM radio signal, to demodulate this signal and recover the RBDS message (bits), and to decode these bits into a text message that is understandable by any u

This newly revised and expanded edition of the 2003 Artech House classic, Radio Frequency Integrated Circuit Design, serves as an up-to-date, practical reference for complete RFIC know-how. The second edition includes numerous updates, including greater coverage of CMOS PA design, RFIC design with on-chip components, and more worked examples with simulation results. By emphasizing working designs, this book practically transports you into the authorsOCO own RFIC lab so you can fully understand the function of each design detailed in this book. Among the RFIC designs examined are RF integrated LC-based filters, VCO automatic amplitude control loops, and fully integrated transformer-based circuits, as well as image reject mixers and power amplifiers.If you are new to RFIC design, you can benefit from the introduction to basic theory so you can quickly come up to speed on how RFICs perform and work together in a communications device. A thorough examination of RFIC technology guides you in knowing when RFICs are the right choice for designing a communication device.
