Abstract:  By using nonlinear map—Arnold cat map as the coupling method between lattices and integral Logistic function and integral Tent function as the nonlinear function, this paper proposes the integral nonlinear coupled map lattices model based on the typical spatiotemporal chaos model—coupled map lattices model. The features of the proposed model include uniform distribution and independence. The mutual information between lattices, the distribution character, the difference characteristics, and randomness are measured to investigate the chaotic behaviors of the proposed system. The simulation results indicate that the proposed model is able to generate excellent pseudo-random sequences in parallel and each sequence is independent with others.
