Abstract :
A main disadvantage of multicarrier modulation is that it exhibits a high peak-to-average power ratio (PAPR). This paper analyzes the PAPR complementary cumulative distribution function of MC-CDMA signal by using Golay code as spreading code, which is compared with that of Walsh-Hadmard code, and the performances of two systems in multipath channel are analyzed. Simulation results show that the uplink PAPR of MC-CDMA system using Golay code as spreading code is reduced 3 dB and there is no performance lost compared with that using WH code.
