Adaptive MC-CDMA for NGN

MC-CDMA is a promising candidate for the next generation network (NGN). 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. In this paper, we compare the BER performance of our system to conventional MC- CDMA and our system is found to be much better.
