Radio Monitoring

Radio Monitoring: Problems, Methods, and Equipment offers a unified approach to fundamental aspects of Automated Radio Monitoring (ARM). The authors discuss the development, modeling, design, and manufacture of ARM systems. Data from established and recent research are presented and recommendations are made on methods and approaches for solving common problems in ARM. The authors also provide classification and detailed descriptions of modern high-efficient hardware-software ARM equipment, including the equipment for detection, radio direction-finding, parameters measurement and their analysis, and the identification and localization of the electromagnetic field sources. Examples of ARM equipment structure, applications, and software are provided to manage a variety of complicated interference environment in the industrial centers, inside of the buildings, and in the open terrain. This book provides a reference for professionals and researchers interested in deploying ARM technology as a tool for solving problems from radio frequency spectrum usage control.

This book discusses the architecture of modern automated systems for spectrum monitoring including automation components: technical means for spectrum monitoring, special software and engineering infrastructure. The problems of automated system development for search and localization of unauthorized radio emission sources in open localities, mathematical methods and algorithms for modulation of parameter measurements for wireless communication as well as issues of identification and localization of radio emission sources are considered. Constructive solutions and modern technical means for radio monitoring and their application are given. Numerous examples are described for the implementation of automated systems, digital radio receivers and radio direction-finders, analyzers of parameters for GSM, CDMA, LTE, DVB-T/T2, Wi-Fi, DMR, P25, TETRA and DECT signals. Practical implementations of the described methods are presented in applied software packages and in radio monitoring equipment.

Radio monitoring is an important feature of broadcasting history and monitoring reports form a treasure trove for historians. This volume offers six case studies that provide new insights on the importance of radio monitoring during the Second World War and the Cold War. Radio broadcasting is not only about transmission, but also about listening. From the start of the medium’s history, radio organisations institutionalised services to monitor the broadcasts of stations from all over the globe and write daily reports about them. This act of listening provided valuable information about the situation in various parts of the world or insights into the communication strategies of broadcasters. As a result, collections of monitoring reports are bulky, containing countless documents which form a treasure trove for radio historians. At the same time researchers need to be aware that these sources are far from neutral: monitoring services often serve clear geopolitical objectives in context of conflict situations. This volume explores the rich history of radio monitoring during the Second World War and the Cold War. As such it offers original case studies that shed light on previously unknown radio histories. Moreover, all the authors reflect on the use of monitoring reports as a historical source and as such provide methodological guidelines. This volume will be a key resource for academics, researchers, and advanced students of media history, war studies, media studies, sociology, and cultural studies. It was originally published in Media History.

Using the explicit insturctions in this book, you can explore the worlds of espionage, international politics, foreign wars, ships at sea, cellular phone activity, emergency services and any other arena where the airwaves are used to communicate.

This book shall help shortwave listener to identify stations on shortwave. It contains more than 18000 frequencies from 82 Hz to 30000 kHz.

Since the first edition was published, new technologies have emerged, especially in the area of convergence of computing and communications, accompanied by a lot of new technical terms. This third expanded and updated edition has been adaptetd to cope with this situation. The number of entries has been incremented by 35%. This dictionary offers a valuable guide to navigate through the entanglement of German and English terminology. The lexicographic concept (indication of the subject field for every term, short definitions, references to synonyms, antonyms, general and derivative terms) has been maintained, as well as the tabular layout.

Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.

This book reports on the proceeding of the 5th International Conference on Intelligent, Interactive Systems and Applications (IISA 2020), held in Shanghai, China, on September 25–27, 2020. The IISA proceedings, with the latest scientific findings, and methods for solving intriguing problems, are a reference for state-of-the-art works on intelligent and interactive systems. This book covers nine interesting and current topics on different systems’ orientations, including Analytical Systems, Database Management Systems, Electronics Systems, Energy Systems, Intelligent Systems, Network Systems, Optimization Systems, and Pattern Recognition Systems and Applications. The chapters included in this book cover significant recent developments in the field, both in terms of theoretical foundations and their practical application. An important characteristic of the works included here is the novelty of the solution approaches to the most interesting applications of intelligent and interactive systems.
