摘要

为解决DCSK系统中混沌信号比特能量的不恒定会引起估计干扰从而造成误码率下降，同时该系统的传输速率较低，保密性较差这一问题。提出FM调制与改进型的DCSK系统相结合的方法，通过使用FM调制使混沌信号能量保持恒定从而提高了系统误码性能，同时结合使用两条信道的改进型DCSK的方案进一步提高系统传输效率以及系统安全性能。最后通过理论分析与仿真实验结果比较证明了改进后的系统相关性能得到极大提高。

Abstract

The bit energy of chaotic signals in DCSK system is not stable

which will cause the estimation interference and the bit error rate decline. At the same time

the system's transmission rate is lower and the security is poorer compared with other system. In order to solve these problems

a novel FM-DCSK secure communication system was proposed which was combined the FM modulation with the modified DCSK system.The bit energy of signals remained stable by using FM modulation so that the BER performance in such system can be improved. Meanwhile

the system was also combined with the modified DCSK system which uses two-channel scheme

therefore it can improve the transmission efficiency and further improve the security performance. Finally

the theoretical analysis and the simulation results prove that the relative performance in this proposed system can be greatly improved.
