To obtain better evenness,this paper presented an improved algorithm of producing the chaotic pseudorandom sequence based on the analysis of nonlinear dynamic characteristics statistical characteristics of the one-dimensional Logistic map.The arcsine and arccosine transformation were used to enhance the randomness of pseudorandom sequence produced by the one-dimensional Logistic map.The qualitative analysis and the numerical calculation results show that the iterative times has little influence on the statistical characteristics of the improved Logistic map sequence and the better evenness can be obtained with regard to the previous works.
