A novel joint-optimization idea for uplink multicarrier CDMA (MC-CDMA) system is presented in this paper. This idea can greatly mitigate the multiple-access interference (MAI) and improve the system performance. Compared to traditional MC-CDMA systems the optimum system has much better bit error rate performance but also large feedback cost. Then some suboptimum systems are introduced which still have good performance similar to the optimum system and less feedback amount.
