Channel State Information enhanced adaptive MC-CDMA

Future wireless communications will require higher bandwidth and more efficient systems; and MC-CDMA is a good candidate. 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 ldquochannel state information enhanced multi-carrier CDMArdquo is introduced in this paper. Simulated results have shown that the scheme yields a higher system capacity and better BER than a conventional MC-CDMA at various noise scenarios.
