Performance analysis of CDMA systems Systems employing direct sequence CDMA techniques have been proposed for future generation cellular systems, as well as personal communication systems. Accurate analysis of these systems for system design and performance tuning is increasingly important. We have developed methods to analyze direct sequence CDMA systems with different modulation and channel conditions. The capacities of CDMA systems can be significantly increased by optimizing transmitters and receivers to minimize mutual interference among different users. We have developed efficient transmitter and receiver optimization algorithms for direct sequence CDMA systems and multicarrier CDMA systems.
Results show that significant improvement in capacities can be obtained.
