Abstract :
This paper presents an advanced architecture for a residue number system (RNS) based CDMA system for high-rate data transmission by combining RNS representation, PSK/QAM modulation and orthogonal modulation. The proposed system uses a lesser spreading factor than RNS based CDMA and the performance is comparable. The modified system is simulated extensively for different channel conditions and found that it can be used for faster data transmission without affecting the system performance
