Introduction

Increasing demand of high data rates of the system users has been a challenging research area in communication engineering. Various novel techniques haven been developed so for in order to meet the high user’s capacity with lowest possible error performance degradation. For the development of efficient communication systems, effective utilization of communication resources (time and bandwidth) among the system users plays a significant role. Communication resources can be effectively shared using multiple access techniques that include techniques like FDMA, TDMA and CDMA. FDMA was the technique used in the First generation cellular wireless communication systems while hybrid FDMA/TDMA and CDMA has been the method for multiple access used in the Second generation systems. The third generation (3G) cellular wireless communication systems are mostly based on the CDMA technology.

CDMA2000 1x RTT is one of the standards that have been adopted for the 3G cellular wireless communication. The first CDMA cellular standard, IS-95 was published in 1993. CDMA systems based on IS-95 standard and related specifications are referred to as CDMA One systems. CDMA2000 is an improvement on IS-95. It provides significant improvement in voice capacity and expanded data capability, and is backward compatible with IS-95 handsets.

The talk also provides the participants with a in-depth understanding of core concepts of CDMA2000 1x EV-DO based 3-G Cellular Systems. Live demonstration of EV-DO System will also be done.
