Abstract: According to the characteristic of spatiotemporal chaotic sequences produced by coupled map lattices model, based on the binarization method  using sign function, a new binarization  method is proposed. The results of randomness and correlation tests show that the randomness of binary sequences given by the new method is good. Moreover these sequences have good correlation. These facts show that  the new binarization  method proposed in this paper is effective, simple and practive.

Key words: spatiotemporal chaos, binarization method, binary sequences, randomness, coupled map lattices
