RF and Microwave Engineering. Fundamentals of Wireless Communications

This book provides a fundamental and practical introduction to radio frequency and microwave engineering and physical aspects of wireless communication. In this book, the author addresses a wide range of radio-frequency and microwave topics with emphasis on physical aspects including EM and voltage waves, transmission lines, passive circuits, antennas, radio wave propagation. Up-to-date RF design tools like RF circuit simulation, EM simulation and computerized smith charts, are used in various examples to demonstrate how these methods can be applied effectively in RF engineering practice. Design rules and working examples illustrate the theoretical parts. The examples are close to real world problems, so the reader can directly transfer the methods within the context of their own work. At the end of each chapter a list of problems is given in order to deepen the reader's understanding of the chapter material and practice the new competences. Solutions are available on the author's website

Signals & Systems

This book is the second edition of a text designed for undergraduate courses in signals and systems. While such courses are frequently found in electrical engineering curricula, the concepts and techniques that form the core of the subject are of fundamental importance in all engineering disciplines. In fact, the scope of potential and actual applications of the methods of signal and system analysis continues to expand as engineers are confronted with new challenges involving the synthesis or analysis of complex processes. For these reasons we feel that a course in signals and systems not only is an essential element in an engineering program but also can be one of the most rewarding, exciting, and useful courses that engineering students take during their undergraduate education.

Practical Antenna Handbook

Design and construct your own antennas with step-by-step instructions and plans. Joseph J. Carr's Practical Antenna Handbook, Fourth Edition, is an update of the most popular book on antennas ever written. This empowering guide blends theoretical concepts that engineers need to design practical antennas with hard-learned lessons derived from actually building and using antennas -- real antennas, not merely theoretical constructs on a blackboard. Certain to become the toolbox favorite of radio enthusiasts and professionals of all types, from technicians to citizen banders and shortwave listeners, it covers a wide variety of antennas: high-frequency dipole; vertically polarized HF; multiband and tunable wire; hidden and limited space; directional phased vertical and directional beam VHF/UHF transmitting and receiving; shortwave reception; microwave; and mobile, marine, and emergency. This state-of-the-art edition includes a new chapter on antenna modeling software and new coverage of small transmitting antennas and receiving loop antennas.

Communication Systems

This best-selling, easy to read book offers the most complete discussion on the theories and principles behind today's most advanced communications systems. Throughout, Haykin emphasizes the statistical underpinnings of communication theory in a complete and detailed manner. Readers are guided though topics ranging from pulse modulation and passband digital transmission to random processes and error-control coding. The fifth edition has also been revised to include an extensive treatment of digital communications.

Modern Digital and Analog Communication Systems

As engineering students become more and more aware of the important role that communication systems play in modern society, they are increasingly motivated to learn through experimenting with solid, illustrative examples. To captivate students' attention and stimulate their imaginations,Modern Digital and Analog Communication, Fifth Edition, places strong emphasis on connecting fundamental concepts of communication theory to students' daily experiences of communication technologies. The text provides highly relevant information on the operation and features of wireless cellular systems, Wi-Fi access, broadband Internet services, and more.

5G LTE Narrowband Internet of Things (NB-IoT)

This book explains the 3GPP technical specifications for the upcoming 5G Internet of Things (IoT) technology based on latest release which is Release 14. It details the LTE protocol stack of an IoT device, architecture and framework, how they are functioning and communicate with cellular infrastructure, and supported features and capability. NB-IoT is designed to connect a large number of devices in a wide range of application domains forming so-called Internet of Things (IoT). Connected devices are to communicate through cellular infrastructure. This technology is new within the 3GPP specifications and is part of upcoming new wireless technology known as 5G.

Археология Средней Азии: энеолит и бронзовый век

Учебник вводит будущего историка, археолога, этнолога в древности эпохи палеометалла через впечатляющее археологическое наследие обитателей Средней Азии. Формирует у студентов представление об истории региона, прошлое которого реконструируется, преимущественно, на основе вещественных источников. На основе археологических комплексов энеолита и бронзового века (вторая половина V – конец II тыс. до н.э.) воссоздается картина поступательного развития исторических процессов. Учтены важнейшие археологические открытия эпохи палеометалла, новые методы изучения и датирования находок. Композиционно работа рассматривается не по географическим регионам, а по археологическим культурам двух историкокультурных зон: древних земледельцев и скотоводов. Учебник адресован студентам, магистрантам, стажерамисследователям исторических факультетов всех форм высших учебных заведений.

Bayesian Statistics. The Fun Way Understanding Statistics And Probability

The subject of this book, Bayesian statistics, helps us get better at reasoning about uncertainty, just as studying logic in school helps us to see the errors in everyday logical thinking. Given that virtually everyone deals with uncertainty in their daily life, as we just discussed, this makes the audience for this book pretty wide. Data scientists and researchers already using statistics will benefit from a deeper understanding and intuition for how these tools work. Engineers and programmers will learn a lot about how they can better quantify decisions they have to make (I've even used Bayesian analysis to identify causes of software bugs!). Marketers and salespeople can apply the ideas in this book when running A/B tests, trying to understand their audience, and better assessing the value of opportunities.

Asynchronous Programming with C++. Build blazing-fast software with multithreading and asynchronous programming for ultimate efficiency

As hardware advancements continue to accelerate, bringing greater memory capacity and more CPU cores, software must evolve to adapt to efficiently use all available resources and reduce idle CPU cycles. In this book, two seasoned software engineers with about five decades of combined experience will teach you how to implement concurrent and asynchronous solutions in C++. You’ll gain a comprehensive understanding of parallel programming paradigms—covering concurrent, asynchronous, parallel, multithreading, reactive, and event-driven programming, as well as dataflows—and see how threads, processes, and services are related. Moving into the heart of concurrency, the authors will guide you in creating and managing threads and exploring C++’s thread-safety mechanisms, including mutual exclusion, atomic operations, semaphores, condition variables, latches, and barriers.
