Wide-band systems seem set to become the next significant generation in wireless communications. They include both wireless local area networks and cellular systems with a large coverage area and will provide a higher data rate and access to Internet and video services, for example. Although most of the data processing is performed digitally, the requirements and possibilities to implement the analogue part of the radio receiver will be different compared to the second-generation narrow-band receivers. Direct conversion architecture is a distinct candidate for wide-band systems because some non-idealities involved in baseband signal processing are significantly relaxed. This work analyzes the requirements and feasibility of direct conversion in wide-band systems. The main emphasis is on cellular systems based on direct sequence code division multiple access, but the same principles are generally valid in all receivers for different applications. The basic principles and design methods involved in receiver design are overviewed as well as the most common radio architectures. Also, in a detailed analysis, the fundamental limitations of the direct conversion architecture are analyzed in wide-band signal processing.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is based on my doctoral thesis at the Helsinki University of Technology. Several different projects during five years guided me from the basics of the RF IC design to the implementations of highly integrated radio receiver chips. Sharing time and effort between IC and system issues is not always straightforward. I have been lucky to follow both topics and share experiences with diligent and enthusiastic people having different specialities. As a result, this book will cover a wide range of different topics needed in the design of highly integrated radio receivers. Experiences from the first receiver prototypes for the third generation cellular systems form the basis of this book. Most of the issues are directly related to the early proposals of European and Japanese standardization organizations. For example, the chip rate was originally set to 4. 096 Mcps in a wide-band CDMA channel. I have kept that number in the book in most of the examples although it has been later changed to 3. 84 Mcps. I hope that the readers will accept that and the possible other incompabilities to the latest specifications. At least in the research phase the changes even in the most essential requirements are definitely not a rare incident and IC designers should be able to react and modify their designs as soon as they can. 256 pp. Englisch.
