W-CDMA and cdma2000 for 3G Mobile Networks
At the time we were working on third-generation (3G) wireless systems at Lucent Technologies, we realized that there were not many books available on this topic. ITU-R had defined four 3G systems, and published a set of standards in 1999. In most cases, our only sources of information were these standards, which were necessarily quite elaborate and were not available as a single document. The purpose of this book is to fill that void and...

Signal processing for mobile communications
Signal processing (SP) is a key research area in mobile communications. The recent years have known a real explosion in research addressing different aspects of mobile communications signal processing. This area is continuously expanding with emerging applications and services such as interactive multimedia and Internet. SP has to meet the new challenges presented to future mobile communication systems such as very low bit error rates, very...

Next Generation Mobile Systems 3G and Beyond
The aim of this book is not to describe new wireless access technologies that will replace the third generation (3G) technologies, but to describe a complete ecosystem of technologies, including access technologies that will be essential for the development of a new mobile environment beyond the 3G era. The mobile applications currently envisioned for this future platform will be augmented by others that will arise because of the innovative...

Introduction to Wireless Local Loop
LIKE MANY IN THE FIELD of wireless local loop, I gained my expertise in the area of cellular and cordless radio. Onmoving into the wireless local loop environment, my first reaction was to seek a good reference work that would help me understand the concepts and issues behind it. No such work appeared to exist, although many colleagues acknowledged the urgent need for one. This book is an attempt to integrate the knowledge I have gained...

DSP for In-Vehicle and Mobile Systems
Over the past thirty years, much progress has been made in the field of automatic speech recognition (ASR). Research has progressed from basic recognition tasks involving digit strings in clean environments to more demanding and complex tasks involving large vocabulary continuous speech recognition. Yet, limits exist in the ability of these speech recognition systems to perform in real-world settings. Factors such as environmental noise,...
