提出了一种同步混沌扩频CDMA系统。在该系统中，我们使用一个开放流耦合混沌序列作为签名序列。这种耦合映象格子具有较长的混沌过渡期，且易于恢复。研究了该混沌序列的自相关性和互相关性，并与m序列和Gold序列进行了比较。最后，对该系统的误差概率进行了分析。
A synchronous chaotic spread-spectrum CDMA system is presented. In the system, we use an open flow coupled-chaotic sequence as the signature sequence. This coupled map lattices has a long chaotic transient and can be recovered easily. The autocorrelation and cross-correlation properties of the chaotic sequences are investigated and compared to m and Gold sequences. Finally, the error probabilities of the proposed system are analyzed.
