The great success of Internet and mobile cellular communications has opened a new vista for future all-IP wireless applications, being evident in continuously increasing demand for worldwide packet data services in the current 2.5G and 3G networks. It has been clear that the future wireless systems will be operating based mainly if not completely on burst data services carrying multimedia traffics, including voice, data, image and video. The need to support such a great amount of burst-type traffic in wireless channels has already posed a serious challenge to the currently available air-link technologies based on either TDMA or CDMA. There has been some debate in the community on the multiple access technologies most suitable for the Beyond 3G wireless. This book serves as a stimulus to accelerate CDMA technological evolution towards the next generation
Addresses the issues related to the next generation CDMA technologies which will be the key air-link technology in Beyond 3G wireless applications
Focuses on the introduction of several promising new CDMA technologies, such as orthogonal complementary codes based CDMA systems, M-ary CDMA, OFDM-CDMA and LAS-CDMA technologies
Provides a self-contained treatment of the area starting with the basics and progressing step-by-step to the advanced research topics on new generation CDMA systems
This book is suitable for researchers in both academia and industry. Postgraduate and senior undergraduate students. Practising engineers and R&D engineers throughout the telecommunications arena.
