Adaptive MC-CDMA using channel state information

In MC-CDMA systems, each data undergoes a different channel condition and arrives with a different error rate at the base station. By transmitting message data based on the channel state information (CSI), a new data transmission scheme called "adaptive multi-carrier CDMA" is introduced in this paper. Simulated results have shown that the scheme yields a higher system capacity than a conventional MC- CDMA at various noise scenarios.
