摘　　要：针对一种特定的离散时间序列———帐篷映射序列,讨论了其数字产生方法并分析相关特征.仿真结果表明,这种序列较适合于用作扩频通信系统中的扩频地址码和保密通信系统中的加密序列.最后详尽地说明了用DSP产生这种混沌序列的可行性及其实现方法.The digital generation methods and　the correlative properties were discussed for a special kind of time discrete chaotic sequence, named Kent-M sequence. Simulation results demonstrate that this kind of sequence is very fit for the address codes in spread spectrum communication system and the secret sequences in security communication system. Finally the feasibility and realization method of the sequence by DSP were explained.
