| 摘 要： | 基于skew tent映射，提出了一类离散化的有限状态混沌映射，它允许精确的数值计算，没有舍入误差。通过选择合适的参数，该映射能产生全周期长度的序列。实验表明，归一化的序列平均周期对计算机精度不敏感，生成的二进制序列具有良好的相关性能，是扩频码的良好选择。

| Abstract: | In this paper,based on the skew tent map, a class of discretized finite state chaotic maps are proposed which allow an exact numerical study without round_off errors. The map can generate full_of_length period sequences by choosing appropriate parameters. Experiments show that the normalized mean cycle period is insensitive to computer precision and the quantized binary sequence has good correlation properties, which indicates that it is a good candidate for spreading code. |
