Abstract :
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
