High Peak to Average Power Ratio (PAPR) of the transmitted signal is a serious problem in multicarrier systems (MC), such as Orthogonal Frequency Division Multiplexing (OFDM), or in Multi-Carrier Code Division Multiple Access (MC-CDMA) systems, due to large number of subcarriers. This effect is possible reduce with some PAPR reduction techniques. Spreading sequences at the presence of Saleh and Rapp models of high power amplifier (HPA) have big influence on the behavior of system. In this paper we investigate the bit-error-rate (BER) performance of MC-CDMA systems. Basically we can see from simulations that the MC-CDMA system with Iterative algorithm can be providing significantly better results than the MC-CDMA system. The results of our analyses are verified via simulation. : {"references": ["B.Sarala, D.S.Venkateswarulu, \"MC-CDMA PAPR Reduction\nTechniques using discrete transforms and compading\", International\njournal of Distributed and Parallel Systems volume 2, number 6, 18\npages,16 figures, Nov. 2011, ISSN:0976-9757", "C.
