Design of Space-Time Coded Single-Carrier and Multi-Carrier MIMO-CDMA systems

P. Sreesudha, B.L. Malleswari

CDMA is one of the channelization protocols that support more number of users simultaneously and asynchronously. Uses spreading technique that spreads information bearing signals, so that only intended receiver can able to receive it thus provides security. MIMO technology has been widely used in wireless communications provides higher data rate and reliability. In this paper single and multi carrier CDMA systems with multiple antennas has been implemented with Space-Time Coding technology (STC) and simulation results are shown. Rotated QSTBC is outperforming for both single and multi carrier systems.
