摘要: 該文結(jié)合細胞神經(jīng)網(wǎng)絡(luò)(CNN)和擴頻通信系統(tǒng)(SSS)的特點，利用三細胞CNN混沌產(chǎn)生了用于擴頻通信系統(tǒng)的多值隨機碼，文中給出了碼的生成方法并分析了它的性能，仿真結(jié)果表明這種碼性能優(yōu)越，能夠很好地用于擴頻通信系統(tǒng)。Abstract: 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.
