Chapter 1IntroductionThe goal for the next generation of mobile communications system is to seamlessly provide awide variety of communication services to anybody, anywhere, anytime. The intendedservice for next generation mobile phone users include services like transmitting high speeddata, video and multimedia traffic as well as voice signals. The technology needed to tacklethe challenges to make these services available is popularly known as the Third Generation(3G) Cellular Systems. The first generation systems are represented by the analog mobilesystems designed to carry the voice application traffic. Their subsequent digital counterpartsare known as second generation cellular systems. Third generation systems mark asignificant leap, both in applications and capacity, from the current second generationstandards. Whereas the current digital mobile phone systems are optimized for voicecommunications, 3G communicators are oriented towards multimedia message capability.1.1 First Generation Cellular SystemsThe first generation cellular systems generally employ analog Frequency Modulation(FM) techniques. The Advanced Mobile Phone System (AMPS) is the most notable of the1
