Book Description
This comprehensive resource provides the latest information on digitization and reconstruction (D&R) of analog signals in digital radios. Readers learn how to conduct comprehensive analysis, concisely describe the major signal processing procedures carried out in the radios, and demonstrate the dependence of these procedures on the quality of D&R. The book presents and analyzes the most promising and theoretically sound ways to improve the characteristics of D&R circuits and illustrate the influence of these improvements on the capabilities of digital radios. The book is intended to bridge the gap that exists between theorists and practical engineers developing D&R techniques by introducing new signal transmission and reception methods that can effectively utilize the unique capabilities offered by novel digitization and reconstruction techniques.

Book Description
Despite frustrating customers and loss of revenue for telecommunications providers, cellular network congestion has remained a problem for which few solutions have been found. Covering GSM, GPRS, UMTS and beyond 3G systems, this practical book breaks new ground by providing you with proven techniques for decreasing blocking and dropped call rate due to network congestion. Using real measurements, this book clearly shows you that the maximum traffic that can be accommodated in a wireless network is not a constant value and varies significantly.

Book Description
This book is about the technological foundations of the next generation of wireless networks for the mobile Internet. It places special emphasis on physical layer techniques and philosophies used in constructing interference-resistant wireless signals. A theoretical framework is developed around the idea of a post-Shannon approach to designing communications systems, viewing channel phenomena not as sources of degradation but as potential resources for additional information and signal robustness. Calhoun has worked in the wireless industry since 1980. Annotation (c)2003 Book News, Inc., Portland, OR (booknews.com).

Book Description
This book explores Radio Access Networks (RANs) within LMR systems, comprising base stations, mobile radios, and hand portable radios. These components facilitate communication among end users via a network of fixed base stations, antennas, and combining systems strategically placed across radio repeater sites throughout the coverage area. This resource also delves into the consequences of interference, highlighting the painstaking efforts required to diagnose and rectify interference issues through field testing and redesign. The central focus being on the design intricacies of base station antennas and combining systems at densely populated shared radio repeater sites. The book underscores how to identify potential sources of interference from co-located transmitters and receivers, effectively surveying sites to anticipate high-level interfering signals. This critical information forms the foundation for crafting base station antenna and combining systems that curtail interference, subsequently optimizing coverage and minimizing costs. Throughout its pages, the book lays out a detailed roadmap for designing LMR systems resilient to interference. By outlining essential principles and methodologies, the book guides practitioners in creating LMR networks that flawlessly align with end users' communication requirements. The resulting systems not only meet expectations but surpass them, offering the coverage area and communication quality demanded by public safety and utility organizations during critical operations. Ultimately, the book serves as an indispensable resource for engineers, designers, and professionals engaged in crafting LMR systems capable of delivering impeccable performance and reliability.
