The synchronization of spatiotemporal chaos of two arrays of coupled n
onlinear oscillators is achieved by discrete time coupling of individu
al cells of the arrays. This synchronization method is based on the kn
owledge of the local dynamics and can be applied to any type of arrays
where the synchronization properties of the cells are known. Furtherm
ore, we discuss possible applications of synchronizing spatiotemporal
chaos in communication and anticontrol of chaos.
