| 摘要: |
| 分形调制在保密通信中具有广阔的应用前景。介绍了分形调制的原理,讨论了其在多速率分集、抗1/f噪声、抗频率选择性衰落、适用于信道条件复杂的MIMO通信系统等方面的特点。由于作为密钥的小波基任意多,且可根据信道情况在不同的小波基之间跳变,故分形调制具有极强的保密性和抗破译能力。 |

| () |
| Abstract: |
| Fractal modulation has wide application prospect in secure communication.The principle of fractal modulation is introduced,and its characteristics in multi-rate diversity,resisting 1/f noise,anti-frequency-selective fading,and fitting to apply to MIMO communication system with complicated route conditions are discussed.Since wavelet bases as cipher keys are infinite and could be hopped to chose based on different channels,fractal modulation's security and the ability of anti-dawning are emphatically expounded and shown. |
| Key words: secure communication,fractal modulation,multi-rate diversity,anti-dawning,1/f noise |
