Multi-carrier direct sequence code division multiple access (MC/DS CDMA) technique is one of the optimum technique for the reverse link mobile transmission. However, because of multi-carrier property, large PAPR (peak to average ratio) may be generated in MC/DS CDMA system. In this paper, DFT spreading code is applied to reduce high PAPR efficiently. As results, about 6 dB PAPR can be achieved at...
