Abstract :
This paper studied the driving synchronization behavior of coupled logistic-map spatiotemporal chaos. Under appropriate parameters, we modified this coupled-map spatiotemporal chaos so that it could be implemented by digital hardware. We applied this synchronization behavior to a CDMA communication system. For local synchronization detection, we proposed the concept of a cascaded receiver. The computer simulation showed that the digital hardware implementation and cascaded receiver synchronization detection are possible
