摘 要
通过对改进素数码的不同脉冲位置赋予不同的频率，提出了一种新的跳频扩时码.理论分析表明，此跳频码的个数为p3，且有很好的自相关和互相关特性.结说更划导常放对希天数值结果也表明在使来自用双限幅器的前提下，这种跳频扩时码的异步光码分多址系统有良好的性能.给出了针对这种跳频码的编解码器方案.

Abstract:A novel frequency-time spreading code by designating the different frequencies to the different mark positions of the modifi态创音首施纪向价ed prime code is proposed.Theoretical analysis demonstrates that the number of the pro门拿香判良另改创posed codes can amount fo p3.Cross-correlation and the sidelobe of auto-correlation of the proposed code have relatively lower values.The numerical results show that the asynchronous OCDMA system assuming the proposed code reveal excellent performance in the presence of double hard limiters.
Keywords:OCDMA; frequency hopping code; modified prime code; double hard limiters
