宽带混沌信号在通信中的应用
|
摘要
混沌是确定性系统产生的伪随机信号，特别适用于保密通信。目前国内外研究用于混沌通信的混沌信号大部分仍是低频的或低速率的信号，这远不能满足于现代通信对保密性和传输速率的实用化要求，而且目前的混沌通信研究与现代通信技术的结合还不够密切，因此研究宽带混沌信号在混沌通信中的应用很有必要。
本文首先从混沌控制的逆向角度，研究了宽带混沌信号的产生，利用PSpice和Matlab软件对宽带混沌产生电路进行了仿真，发现可以获得宽带混沌信号，且其频谱平坦、自相关性好。然后，基于数字混沌激励和模拟电路结合的混沌产生的机制，实现了宽带混沌信号的同步，且其同步具有良好的鲁棒性。
接着，对以宽带混沌信号为载波的模拟多载波通信机制进行了讨论，并利用Matlab对其在多径无线信道下的误码率进行了仿真，结果表明该系统具有高传输速率和良好的通信特性。
最后，本文把二进制混沌序列作为扩频序列，研究了由基于小波包变换的MC—CDMA演化而来的单载波小波包变换域均衡混沌扩频系统，并利用Matlab进行了系统仿真，获得了其良好结果。
Since chaotic system is a deterministic system, its noise-like behavior can be very suitable for using in secure communication. Most of chaotic signals used in recent chaotic communication study are low frequency or low rate, so they are far from satisfying the practical requirements of modern communication systems in security and rate. For few works focused on combination of chaotic theory and modern communication technology, it is of interest to study the application of the wideband chaotic signals to modern communication.
Firstly, from the point of inverse chaos control, generation of wideband chaotic signals is discussed in this paper. And the simulation of generation circuit of wideband chaotic signals is carried out by means of PSpice and Matlab. Results of the simulation show that a flat frequency spectrum of chaotic signal could be generated in some ways, and its autocorrelation performance of the signal is very well.
Next, the synchronization of wideband chaotic signals can be obtained from an analog chaotic system inspired by digital chaotic signal, and the synchronization is of robust.
After that, an analog multi-carrier communication scheme using wideband chaotic signals as carriers is proposed and discussed. The simulation of the system error probability in wireless multi-path channel shows that the system can work in high data rate and is of good quality.
Finally, another communication scheme ?single carrier chaotic spread spectrum with wavelet packets transform domain equalization is proposed, and its good performance in wireless multi-path channel is showed through simulating the system.
