In June 2000, GTEL (Wireless Telecommunications Research Group) at the F- eral University of Ceara ´ was founded by Professor Rodrigo Cavalcanti and his c- leagues with the mission of developing wireless communications technology and impact the development of the Brazilian telecommunications sector. From the start, this research effort has been supported by Ericsson Research providing a dynamic environment where academia and industry together can address timely and relevant research challenges. This book summarized much of the research output that has resulted from GTEL s efforts. It provides a comprehensive treatment of the physical and multiple access layers in mobile communication systems describing different generations of systems but with a focus on 3G systems. The team of Professor C- alcanti has contributed scienti cally to the development of this eld and built up an impressive expertise. In the chapters that follow, they share their views and kno- edge on the underlying principles and technical trade-offs when designing the air interface of 3G systems. The complexity of 3G systems and the interaction between the physical and m- tiple access layers present a tremendous challenge when modeling, designing, and analyzing the mobile communication system. Herein, the authors tackle this pr- lem in an impressive manner. Their work is very much in line with the developments in 3GPP providing a deeper understanding of the evolution of 3G and also future enhancements.
Optimizing Wireless Communication Systems presents the underlying technological breakthroughs that allowed the current state of wireless technology development to evolve. The focus is on the two lower layers of the ISO/OSI layered model, specifically the physical and data link layers including the link and media access control sublayers. These two layers are of particular importance to wireless systems due to the spectrum shortage, the broadcast nature of interference, and time variability in the wireless channel.
The material is divided into two parts. First, is the section on Resource Allocation, which is also known as Radio Resource Management or RRM, that discusses how to increase spectrum efficiency. It also presents solutions for performance optimization in mobile communication standards such as GSM, EDGE, WCDMA, HSPA and LTE. The second section is Transceiver Architectures, which covers wireless link capacity related to OFDM and MIMO. Each chapter within the book includes state-of-the-art concepts, introductory sections to the basics, and references for further reading. Several chapters also include technical details from various standards along with performance results and case studies.
Optimizing Wireless Communication Systems is for researchers and practitioners in the field of wireless communications involved with the design and optimization of current and emerging wireless access technologies for mobile communications.
