摘要

多载波码分多址(MC-CDMA)系统因其在无线通信中的高数据速率而受到广泛关注，研究人员试图提高这些系统的性能。提出了一种具有低峰均功率比的新型MC-CDMA。该系统采用MC-CDMA与单载波频分多址(SC-FDMA)相结合的方式设计，因为后者具有较低的PAPR。在瑞利衰落信道和AWGN信道上对系统进行了仿真，对系统的主要性能进行了评价，并给出了不同信噪比下系统的误码率。最后，对比了原MC-CDMA的PAPR降低情况。

A novel PAPR reduction in MC-CDMA system using Single carrier FDMA technique

According to the fact that Multi-carrier code division multiple access (MC-CDMA) systems receive a great attention due to their achieving high data rates in wireless telecommunications, the researchers try to improve the performance of these systems. This paper presents a novel MC-CDMA which has low peak to average power ratio (PAPR). The system is designed by combining MC-CDMA with the Single carrier-frequency division multiple access (SC-FDMA) because the later has low PAPR. The system is simulated to broadcast on Rayleigh fading and AWGN channel, the main performances of this system are evaluated and the bit error rate of the system is showed at different values of signal to noise ratio. Finally, the reduction in PAPR is showed and compared to the original MC-CDMA.
