| Abstract: | The chaotic sequences generated by spatiotemporal chaotic system model based on two-dimensional coupled map lattice(CML) have good pseudorandom property.In the paper,we analyze in detail the binaryzation way of spatiotemporal sequences,linear complexity,balance character,run-length distribution and its correlation.The research shows that two-dimensional spatiotemporal chaotic sequence has better random character and higher linear complexity than one-dimensional spatiotemporal chaotic sequence and Logistic s... |
