Ultra-wideband (UWB) has been among the most controversial technologies of modern times. Its applications seem endless, its capabilities miraculous and yet it is so poorly understood. In this volume, the authors combine talents to de-mystify ultra-wideband radio and explain it in language that is accessible to non-technologists as well as technologists. They contrast UWB with conventional radio technology so that fundamental, technically accurate information devoid of specific technical and analytical details is accessible for marketing managers, business developers, engineering managers,...

3^rd generation radio systems will be increasingly developed, deployed and operated in the years to come. TDD is one of two main approaches to implementing these 3G systems, so that there will be an increasing need for the engineering community to learn quickly and comprehensively about the TDD technology. As 3G systems become popular, the topics will no doubt be introduced to academic curricula and will also provide a basis for future research.

This book provides comprehensive coverage of TDD. It is essentially a Radio Access Network technology and the book embraces the...

MMS has evolved from the huge popularity of the SMS text service for GSM networks. It is a departure from the transport mechanism used for SMS (which is based on the GSM signalling channels) to the use of IP to transport messages within the MMS network. To this end MMS has similarities with Internet email and standard IETF protocols. As with any new technology it is difficult to accurately predict the position within the next 5 years, although based on previous experience with WAP and SMS it would be fair to say that these protocols will increase in usage over the next 5 years and become...

WCDMA (Wideband Code Division Multiple Access), an ITU standard derived from code division multiple access (CDMA) is officially known as IMT-2000 direct spread. WCDMA is a third generation mobile wireless technology offering much higher data speeds to mobile and portable wireless devices than commonly offered in today's market. WCDMA is a relatively new technology and there is little information in the public domain about specific design issues. The proposed book will discuss UMTS/WCDMA from the perspective of a potential development engineer, who may have experience of GSM but none of WCDMA...

"By 2008, some 2 billion people will be using mobile phones and devices, in many cases to access advanced data services. Against this backdrop, the need for efficient and effective network design will be critical to the success of increasingly complex mobile networks."

Simon Beresford-Wylie (SVP, Nokia Networks)

With the complexity of the cellular networks increasing day by day, a deeper understanding of the design and performance of end-to-end cellular networks is required. Moreover, all the types of networks from 2G-2.5G-3G seem to co-exist. Fundamentals of...

This volume is dedicated to a range of CDMA and MC-CDMA transmission aspects of systems designed for communicating over fading wireless channels.

Currently, a technical in-depth book on this subject, which has a similar detailed exposure of the recent advances in CDMA, M-ary CDMA and MC-CDMA, is unavailable. A further attraction of the joint treatment of these topics is that it allows the reader to view their design trade-offs in a comparative context.

Divided into five main parts:

Part I: provides a detailed introduction to the subject of CDMA...

A proven, cost-effective approach to solving analog signal processing design problems

Most design problems involving analog circuits require a great deal of creativity to solve. But, as the authors of this groundbreaking guide demonstrate, finding solutions to most analog signal processing problems does not have to be that difficult.

Analog Signal Processing presents an original, five-step, design-oriented approach to solving analog signal processing problems using standard ICs as building blocks. Unlike most authors who prescribe a "bottom-up" approach, Professors...

A fresh look at electronics in the real world of Electromagnetic interference, the physical environment, and utility power . . .

Despite the many advances in electronics, the semiconductor revolution, and technologies that perform well above 100 MHz--problems of noise and interference remain. One reason is the inability of circuit theory to address a number of real-world issues--utility power, grounding, the character of buildings, the nature of long cables, or questions of radiation vis-a-vis equipment.

Solving Interference Problems in Electronics tackles all these...
