摘要
利用 L ogistic,Tent,chebyshev映射产生直扩码分多址系统的二相混沌扩频序列 .从二相混沌扩频序列平衡性与直扩系统对载波抑制度有密切关系、扩频序列不平衡将使系统载波泄漏增大的角度出发 ,分别分析其平衡性与分形参数、初始值、序列周期的关系 ,并且进行比较 .
In this paper, the 2 Phase frequency spreading sequence for DS/CDMA by using Logistic, Tent, chebyshey mapping is discussed. The relation between the performance of balance of the sequence and fractal parameter, initial value, the period of sequence is analysed thus pvoviding a reference basis for frequency spread seguence selecting the chaotic.
