Antennas and Propagation for Wireless Communication Systems: 2nd Edition
Antennas and Propagation for Wireless Communication Systems: 2nd Edition

Antennas and propagation are o covf fundamental importance to theerage, capacity and quality of all wireless communication systems. This book provides a solid grounding in antennas and propagation, covering terrestrial and satellite radio systems in both mobile and fixed contexts. Building on the highly successful first edition, this fully updated text features significant new material and brand new exercises and supplementary materials to support course tutors. A vital source of information for practising and aspiring wireless communication engineers as well as for students at postgraduate and senior undergraduate levels, this book provides a fundamental grounding in the principles of antennas and propagation without excessive recourse to mathematics. It also equips the reader with practical prediction techniques for the design and analysis of a very wide range of common wireless communication systems.

Including:
  • Overview of the fundamental electromagnetic principles underlying propagation and antennas.
  • Basic concepts of antennas and their application to specific wireless systems.
  • Propagation measurement, modelling and prediction for fixed links, macrocells, microcells, picocells and megacells
  • Narrowband and wideband channel modelling and the effect of the channel on communication system performance.
  • Methods that overcome and transform channel impairments to enhance performance using diversity, adaptive antennas and equalisers.


Key second edition updates:
  • New chapters on Antennas for Mobile Systems and Channel Measurements for Mobile Radio Systems.
  • Coverage of new technologies, including MIMO antenna systems, Ultra Wideband (UWB) and the OFDM technology used in Wi-Fi and WiMax systems.
  • Many new propagation models for macrocells, microcells and picocells.
  • Fully revised and expanded end-of-chapter exercises.
  • Solutions manual and presentation slides available online for course tutors.

Advanced Microsystems for Automotive Applications 2008

With the total number of vehicles steadily increasing and soon approaching one billion, the world is facing serious challenges in terms of both safety of road transport and sustainability. Consequently the two major persistent issues for the automotive industry are improved safety and reduced emissions.
The integration of complex microsystems with enhanced intelligence, so-called smart systems has enabled an increase of efficiency of the previously dumb internal combustion engine by on average 1% annually during the last 20 years. In the future, smart systems may help to leverage novel powertrain concepts towards the zero emissions vehicle. Particularly for electric vehicles, anticipatory power management and efficient driving assistance by smart systems will be needed to overcome the range limitations. Adaptive systems predicting the energy demand for a chosen route will help the driver to increase energy efficiency. Networked devices for car-to-car communication could help to avoid the waste of energy due to unnecessary braking and accelerating. Intelligent systems for tire monitoring and control deserve special attention since insufficient tire pressure accounts for more than 3% of the efficiency losses in the car. Future electrical in-wheel motors require new miniaturised functionalities enabled by advanced micro- and smart systems.
The conference book in hand is a showroom of activities, the AMAA has been known for during the last 12 years: advanced sensors even including one based on the giant magneto resistance (GMR) effect  a finding for which two European physicists were awarded the Nobel prize, recently  several camera and radar systems making road traffic safer by assisting the driver in recognizing pedestrians and obstacles, and human-machine interfaces based on the recognition of hand gestures - a striking example of how smart systems will further enhance the usability of vehicles and the comfort of driving

Intelligent Complex Adaptive Systems

The universe is a massive system of systems -- for example, ecological systems, social systems, commodity and stock markets. These systems are complex, constantly adapting to their environment, and many are essential to the very existence of human beings. To fully understand these systems, complex adaptive systems research uses systemic inquiry to build multi-level and multidisciplinary representations of reality to study these systems

Microwave Engineering

Focusing on the design of microwave circuits and components, this valuable reference offers professionals and students an introduction to the fundamental concepts necessary for real world design. The author successfully introduces Maxwell's equations, wave propagation, network analysis, and design principles as applied to modern microwave engineering. A considerable amount of material in this book is related to the design of specific microwave circuits and components, for both practical and motivational value. It also presents the analysis and logic behind these designs so that the reader can see and understand the process of applying the fundamental concepts to arrive at useful results. The derivations are well laid out and the majority of each chapter's formulas are displayed in a nice tabular format every few pages. This Third Edition offers greatly expanded coverage with new material on: Noise; Nonlinear effects; RF MEMs; transistor power amplifiers; FET mixers; oscillator phase noise; transistor oscillators and frequency multiplier.

Practical and Experimental Robotics

Taking a completely hands-on approach, using cheap and easily available robotics kits, Practical and Experimental Robotics provides a detailed exploration of the construction, theory, and experiments for different types of robots. With topics ranging from basic stamp microcontrollers to biped and propeller based robots, the text contains laboratory experiments, examples with solutions, and case studies. The authors begin with a review of the essential elements of electronics and mechanics. They describe the basic mechanical construction and electrical control of the robot, then give at least one example of how to operate the robot using microcontrollers or software. The book includes a reference chapter on Basic Stamp Microcontollers with example code pieces and a chapter completely devoted to PC interfacing. Each chapter begins with the fundamentals, then moves on to advanced topics, thus building a foundation for learning from the ground up. Building a bridge between technicians who have hands-on experience and engineers with a deeper insight into the workings, the book covers a range of machines, from arm, wheel, and leg robots to flying robots and robotic submarines and boats. Unlike most books in this field, this one offers a complete set of topics from electronics, mechanics, and computer interface and programming, making it an independent source for knowledge and understanding of robotics
