As the demand for and the variety of 3G services increase, more advanced hardware and software technologies will be needed to enhance the mobile radio communications infrastructure. This forward-looking book delivers a comprehensive overview of the advanced technologies driving the evolution of mobile radio access networks, focusing on high-level architectural issues and system engineering. The book highlights the advantages and drawbacks of these advanced technologies and helps you make strategic decisions on R&D planning and system deployment.
By striking a balance between theory and practice, and between technology and economics, it addresses the concerns of system engineering, research and development, and telecom management and analysis. The book covers the critical topics you need to understand for your work in the field, from linear transmitters and radio-over-fiber, to software radio base station and mobile terminal positioning. This unique resource examines such cutting-edge technologies as HSDPA, MIMO, OFDM, and IP based RAN, and presents new concepts in both autonomic and ubiquitous networks.
A generous amount of case study material is presented, including a ‘what went wrong in the design process’ discussion, when applicable. Color plots of current density and various field quantities included throughout the book help you better understand the fundamental behavior of the circuits being studied. Stress is given to the impact of meshing, geometrical resolution and convergence on the solution process, showing you that you can better control and greatly influence the quality and speed of the solution. You’ll appreciate solving problems using the fundamental, underlying physics, rather than the more approximate methods used in the past. Specific design information on transitions in multilayer PCBs and PCB connectors is not available in any other book.
By programming the digital synthesizers and transmitters, adaptive channel bandwidths, modulation formats, frequency hopping and data rates are easily achieved. Techniques such as digital predistortion for power amplifier linearization, digital compensation methods for analog I/Q modulator nonlinearities and digital power control and ramping are presented in this book. The flexibility of the digital synthesizers and transmitters makes them ideal as signal generators for software radio. Software radios represent a major change in the design paradigm for radios in which a large portion of the functionality is implemented through programmable signal processing devices, giving the radio the ability to change its operating parameters to accommodate new features and capabilities. A software radio approach reduces the content of radio frequency (RF) and other analog components of traditional radios and emphasizes digital signal processing to enhance overall transmitter flexibility. Software radios are emerging in commercial and military infrastructure.
You cannot design or build anything without testing it. The test equipment manufacturers do a great job of providing equipment, but this book helps explain what the equipment is, how it works, and how to use it. It’s a good addition to your wireless library.” (Electronic Design, December 10, 2008)
