Abstract—MC-CDMA is the most promising technique for high bit rate and capacity transmission in wireless communication. One of the challenging issues of MC-CDMA system is the very high PAPR due to the large number of sub-carriers which reduces the system efficiency. In our work, a new (SLM-PTS) method is suggested with one IFFT block for PAPR reduction in MC-CDMA downlink transmission. The new method has showed a significant improvement in PAPR reduction performance and system complexity. SLM-PTS is compared to PTS and SLM at the term of PAPR reduction, as well as it is compared to the original system at the term of bit-error-rate (BER), firstly, without and then using the linear amplifier (SSPA).
Index Terms—IFFT, MC-CDMA, PAPR, PTS, SLM, SSPA.
