At the present time, the wireless communications research community and industry are about to start discussions on standardization activities for the fourth generation (4G) of these systems. In the past, the term ‘new generation’ referred to mobile cellular communications. At this stage in the evolution of wireless communications, there is a tendency to agree that 4G will integrate mobile communications specified by the International Mobile Telecommunications (IMT) standard and Wireless Local Area Networks (WLAN) or, in general, Broadband Radio Access Networks (BRAN). The focus of this book is on the system elements that provide adaptability and reconfigurability and discussion of how much these features can improve the system performance. Chapter 1 starts with a generic 4G system concept that integrates available advanced technologies and then focuses on system adaptability and reconfiguration as a possible option to meet a variety of service requirements, available resources and channel conditions. Chapter 2 introduces adaptive coding. Chapter 3 covers adaptive and reconfigurable modulation. Chapter 4 introduces space-time coding. Chapter 5 covers code division multiple access (CDMA). Chapter 6 deals with time division multiple access (TDMA). Chapter 7 covers orthogonal frequency multiplexing (OFDM) and multi-carrier CDMA. Chapter 8 introduces ultra wideband radio with topics such as UWB multiple access in Gaussian channels, the UWB channel, a UWB system with M-ary modulation, M-ary PPM UWB multiple access, coded UWB schemes and multi-user detection in UWB radio. Chapter 9 covers antenna array signal processing with focus on space-time receivers for CDMA communications. Chapter 10 discusses adaptive/reconfigurable software radio. Chapter 11 provides examples of software radio architectures. Chapter 12 covers some selected issues for network overlay in 4G. Chapter 13 presents the problem of user location in 4G networks. Chapter 14 discusses channel modeling and measurements for 4G. Chapter 15 includes discussions on adaptive 4G networks.

Modern Microwave Circuits

This book addresses the analysis techniques and practical applications of microwave printed passive circuits. Instead of focusing mainly on printed circuits, a much broader scope has been adopted, so that a wide audience from research students to design engineers can profit from it. As much balance between theory and applications as possible has been kept. Each chapter can be studied independently without losing coherency. The book promotes microstrip circuits and the usage of computer simulations in microwave printed circuit design. Chapter 1 provides a brief introduction to microwave circuit theory. Practical topics such as network analyzer calibration methods and matching circuits are included as well as network synthesis. Chapter 2 sets the stage for microwave printed circuits, which are the main theme of the book. Chapter 3 covers full-wave analysis methods of microwave printed circuits in detail, including the concept of Green’s function. Chapter 4 presents microstrip antennas, including an emphasis on bandwidth enhancement methods. Chapter 5 contains various topics on microstrip-coupled lines. The multi-conductor transmission line analysis technique is included to address the growing applications of high frequency coupled-transmission lines such as flex-cables or unshielded twisted pair (UTP). Chapter 6 is a classical introduction to filter theory and microstrip filters. Modern filter design techniques, such as cascaded triplets and quadruplets are also found in this chapter. Chapter 7 is devoted to microwave passive elements, another growing area of microwave engineering, due to advances in MMIC technology. Apart from mentioning basic lumped elements, this chapter also introduces model extraction techniques for passive elements. This could be useful to designers who want to extract equivalent lumped element models for their particular application. A method, which is commonly used in other areas of engineering, but not too much in electrical engineering, namely dimensional analysis, concludes this chapter.
