摘要
分析了多载波码分多址(MC-CDMA)系统模型及扩频码序列性能,根据MC-CDMA系统特点,研究了采用GOLAY码、Gold码及Walsh码等不同扩频序列及不同序列长度对MC-CDMA系统峰均比的影响。仿真分析了序列长度为16、32及64位时MC-CDMA系统峰均比性能。
The characteristics of various spread code sequences such as GLAY,GOLD and Walsh codes and the influences of these codes on the peak average power ratio （PAPR） of MC-CDMA system are analyzed in this paper. The PAPR property of MC-CDMA system is simulated by using different spread code sequence lengths of 16,32 and 64-bit. This study and the result could serve as a reference for future work.
