| Abstract: | The characteristics of various spread code sequences such as GLAY,GOLD and Walsh codes and the influences of these codes on the peak average power ratio （PAPR） of MC-CDMA system are analyzed in this paper. The PAPR property of MC-CDMA system is simulated by using different spread code sequence lengths of 16,32 and 64-bit. This study and the result could serve as a reference for future work. |
