| 摘 要： | 将混沌映射ICMIC应用于CDMA系统，产生相应的ICMIC二元扩频序列，并对系统的抗干扰性能以及系统容量进行了分析，分析表明，与Logistic周期混沌扩频序列、传统的EOE－Gold序列相比，该扩频序列具有良好的自相关与互相关特性，可以有效地抑制多径干扰和多址干扰，并使扩频通信系统的信道容量得到提高，对CDMA系统性能的改善起到重要的作用。

| Abstract: | Binary spreading sequences generated from ICMIC chaotic map are analyzed. The analysis shows that they have good autocorrelation and cr osscorrelati on characteristics. Compared with spreading sequences generated from Logistic ma p and EOE-Gold sequences, ICMIC binary spreading sequences can efficiently redu ce the multiple path and multiple access interference and increase th e channel capability of spreading communication system. The spreading sequences have great influences in performance improvement of CDMA system. |
