Excerpt from Measurements to Support Modulated-Signal Radio Transmissions for the Public-Safety Sector This is the fifth in a series of nist Technical Notes (tn) on propagation and detection of radio signals in large building structures. This series has been developed to support improved radio communications for the public-safety community in difficult radio environments. The first, second, and third nist Technical Notes (nist TN 1540, 1541, and 1542) described experiments that measured received signal strength in structures before, during, and after implosion. The fourth, nist Technical Note 1545, describes a series of signal-strength measurements carried out in 14 large public buildings. The first four Technical Notes have created a large, public-domain data set describing the attenuation of radio signals in various building types for the public safety and cellular telephone bands. The present document augments this work by providing additional data that are relevant to modulated-signal communication measurement and simulation for the public-safety sector. We describe measurements of three large public buildings and one subterranean tunnel. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Measurements to Support Public Safety Communications: Attenuation and Variability of 750 Mhz Radio Wave Signals in Four Large Building Structures This is the sixth in a series of nist technical notes (tn) on propagation and detection of radio signals in large building structures (apartment complex, hotel, office buildings, sports stadium, shopping mall, etc). The first, second, and third nist Tech Notes (nist TN 1540, nist TN 1541, and nist TN 1542) described experiments related to radio propagation in a structure before, during, and after implosion. The next two Tech Notes (nist TN 1545 and nist TN 1546) focused exclusively on RF propagation into large buildings, with no implosion results. These reports are intended to give first responders and system designers a better understanding of what to expect from the radio-propagation environment in disaster situations. The overall goal of this project is to create a large, public-domain data set describing the attenuation and variability of radio signals in various building types in the public safety frequency bands.

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.

In response to a request from the Defense Advanced Research Projects Agency, the committee studied a range of issues to help identify what strategies the Department of Defense might follow to meet its need for flexible, rapidly deployable communications systems. Taking into account the military's particular requirements for security, interoperability, and other capabilities as well as the extent to which commercial technology development can be expected to support these and related needs, the book recommends systems and component research as well as organizational changes to help the DOD field state-of-the-art, cost-effective untethered communications systems. In addition to advising DARPA on where its investment in information technology for mobile wireless communications systems can have the greatest impact, the book explores the evolution of wireless technology, the often fruitful synergy between commercial and military research and development efforts, and the technical challenges still to be overcome in making the dream of "anytime, anywhere" communications a reality.

Wireless technology is a truly revolutionary paradigm shift, enabling multimedia communications between people and devices from any location. It also underpins exciting applications such as sensor networks, smart homes, telemedicine, and automated highways. This book provides a comprehensive introduction to the underlying theory, design techniques and analytical tools of wireless communications, focusing primarily on the core principles of wireless system design. The book begins with an overview of wireless systems and standards. The characteristics of the wireless channel are then described, including their fundamental capacity limits. Various modulation, coding, and signal processing schemes are then discussed in detail, including state-of-the-art adaptive modulation, multicarrier, spread spectrum, and multiple antenna techniques. The concluding chapters deal with multiuser communications, cellular system design, and ad-hoc network design. Design insights and tradeoffs are emphasized throughout the book. It contains many worked examples, over 200 figures, almost 300 homework exercises, over 700 references, and is an ideal textbook for students.

With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The treatment is therefore less focused on the mathematics and more on the conceptual aspects, the idea being to allow the readers to think about the subject at a higher conceptual level, thus building the foundations for more advanced topics. The book remains an engineering text, with the goal of helping students solve real-world problems. In this vein, the last chapter pulls together the individual topics as discussed throughout the book into an in-depth look at the development of an end-to-end communication system, namely, a modem for communicating digital information over an analog channel.
