The expanded use of digital signal processing techniques has spawned cell phones and wireless data transceivers that offer incredible performance and features at a per-unit cost that puts them within reach of nearly everyone. However, these low per-unit costs are achieved through mass production of hundreds of thousands or even millions of units from a single design. The design of a new cell phone or wireless modem for a PDA is a very complex and expensive affair. Because of the complexity in these devices, it is not practical to breadboard prototypes for testing until after the design has been exhaustively tested and honed using simulation. Simulating Wireless Communication Systems has been carefully crafted to serve as a convenient reference for communications engineers and system designers faced with the need to simulate a wireless communication system or one of its major subsystems. The primary focus of the book is emphasized by the chosen subtitle, Practical Models in C++. This book presents nearly two hundred detailed mathematical models of practical devices that are used to implement wireless communication systems. Ready-to-run software modules that implement these models are provided on the companion website. A number of appendices provide convenient access to mathematical and statistical information that may be useful in the understanding, setup, and use of the various models.
Next-generation mobile communications are likely to employ different techniques and standards. The implementation in software of as many receiver functionalities as possible appears to be the most effective solution for coping with the multiplicity of communications alternatives. The concept of software radio, dating back to 1991, originally attracted commercial interest owing to the possibility that transmission layer functions could be fully software-defined. The same approach can be extended to protocols of the higher layers too, thus conceiving a programmable hardware to implement the functionalities of several layers of protocols by resident software or software downloaded from the network. Consisting of selected technical contributions to the Workshop on "Software Radio", this volume deals with state-of-the-art surveys of the enabling technologies and the prospective services of software radio implementations for future mobile communications. Original and state-of-the-art research and development is presented in fields such as: - Software radio for universal wireless internet access - Software radio for multimedia communications - Software radio architecture - Network architecture, protocols and services - Software radio technology towards pervasive appliance. This volume on software radio is a valuable reference for both researchers and telecommunications professionals.
Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.
This book (part of a comprehensive 4-volume series) provides the latest details and covers the most impactful aspects of mobile, wireless, and broadband communications development. These books present key systems and enabling technologies in a clear and accessible manner, offering you a detailed roadmap the future evolution of next generation communications.
Look to this cutting-edge new resource for a comprehensive description of TDD-CDMA technology. The book provides you with in-depth coverage of the important TDD-based standards, including the 3GPP's TD-CDMA for UMTS, and TD-SCDMA, the Chinese 3G standard. You gain a thorough understanding of the differences between the TDD and FDD modes of CDMA, and discover the advantages of TD-CDMA and TD-SCDMA in 3G systems. What's more, you find keen insight into the future research directions and prospects for 4G networks.
This book helps readers do just that by: providing a comprehensive introduction to multicarrier techniques for 4G mobile communications with a special focus on the analytical aspects; explaining radio channel characteristics and phenomena and discussing the advantages and disadvantages of the OFDM scheme; featuring new multicarrier-related techniques, MC-CDMA, research on several 4G systems, and a look at several problems to be overcome with these systems; examining the concept and detail of the ODFM scheme and how to carry out theoretical analysis on the performance of transmission systems in radio channels; showing how ODFM has been successfully adopted as a modulation scheme in communications systems and broadcasting systems such as ADSL, wireless LANs, and DVB-T."--Jacket.
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.
