Abstract: A main disadvantage of multicarrier modulation is that it exhibits a high peak to average power ratio(PAPR). It is presented in this paper that with Golay code as spread code for MC-CDMA system,PARA can be reduced.The analysis and comparison of the PARA complementary cumulative distribution function(CCDF)of MC-CDMA signal by using Golay code and Walsh-Hadmard code respectively as spread code,and the performances of two systems in multipath fading channel are given.Simulation results show that there is 3dB reduction in the uplink PAPR of MC-CDMA system using Golay code and no performance lost compared to the system using WH code.

Key words: peak-to-average power ratio(PAPR), complementary cumulative distribution function(CCDF), Golay code, WH code, multipath channel
