摘　　要：该文结合细胞神经网络(CNN)和扩频通信系统(SSS)的特点,利用三细胞CNN混沌产生了用于扩频通信系统的多值随机码,文中给出了码的生成方法并分析了它的性能,仿真结果表明这种码性能优越,能够很好地用于扩频通信系统。This paper puts forward a new multilevel chaotic sequence and a multifunction circuit using three-cell CNN chaos, combining the characteristic of CNN with that of the Spread Spectrum System (SSS). It also proposes a scheme of generating the Multilevel Chaotic Sequence (MCS) and analyzes its properties. Simulation results show that this kind of sequence performs quite well, which is suitable for future large-capacity SSS.
