The theoretical analysis shows that the chaotic sequences serve as spreading codes for A-CDMA.
理论分析表明,该混沌序列具有较理想的A - CD MA扩频码性能。
In spreading code design, MAI and ISI are removed by constructing spreading codes with zero correlation window, which increases system capacity.
在扩频码设计中,通过构造零相关窗码可以消除MAI和ISI,从而提高系统容量。
However, the code resource is very limited for ZCW spreading codes and the complexity of joint detection is huge when the number of code channels takes large.
但二者都有一定局限性,对于零相关窗码来说,它的码字资源十分有限,对于联合检测来说,当用户数很大,它的复杂度不能容忍。
