摘要
本文对Chebyshev混沌二进制序列伪随机码的统计特性进行分析,并与改进Logistic混沌进制序列伪随机码的自相关、互相关、游程、平衡特性等特性进行了比较。研究证明,Chebyshev序列性能优良,在扩频通信中具有较高的应用价值。
In the paper,we analyze the statistic characteristic of chaotic sequences generated by the Chebyshev binary chaotic PN sequence and compare with the improved logistic binary chaotic PN sequence in respect of the performance of autocorrelation, crosscorrelation, run and balance. It is pointed out that the excellent performance of Chebyshevt sequence makes it highly applicable in spread spectrum communication.
