| 摘 要： | 为在实际信道传输时减少加性噪声对ＣＮＮ混沌保密通信系统性能的影响，在接收端使用限带滤波器并用频带补偿法来保证ＣＮＮ混沌系统的自同步，从而在用参数调制法作为加密方案的保密通信系统中获得解调性能的提高．理论与数值模拟结果表明，参数调制法确实减小了系统的同步及解调误差．

| Abstract: | Cellular neuralnetworks (CNN) chaotic secure com m unication is a new secure com m unication schem e based on chaotic synchronization. Aband lim itfilterwasused atthe receiverside ofthe system in order to reduceeffectofchannelnoise, and theself synchronization ofCNNchaoticsystem wasguaranteed by frequency com pensation m ethod. Im provem entofdem odulation perform anceofthesystem w asachieved w hen param eter m odulation was used as encryption schem e. The theoretical and num erical sim ulation resultsshow thatthism ethod has assuredly reduced errorsofsynchronization and dem odulation. |
