Wireless commun ication plays an important role in our daily life.One o f the most important techniques which is Candidate for the fourth generation is Multicarrier Code Div ision Multip le Access (MC-CDMA) due to its high data rate.This research paper presents the MC-CDMA system using different modulation techniques.The variety of modulation types are depended in order to show the effects of modulation index and type on broadcasting data.The bit error rate of the system is plotted for a range of signal to noise ratio so that the effect of modulat ion on the MC-CDMA system will be evident.Actually, the simulat ion results show that QAM gives less bit error rate that makes MC-CDMA more flexib le and suitable for mob ile communicat ion next generation technology.Also, the peak-to-average power (PAPR) of M C-CDMA is analyzed to show that h igh PAPR is the main disadvantage of MC-CDMA system then the possible solutions for this problem are discussed in this research paper.
