| 摘 要： | 随着混沌理论和通信技术的发展，各种通信调制方案的性能也逐渐被人们所研究并掌握。文中通过对现有混沌调制解调方式的分析和研究，将调幅、调频、正交相结合提出了一种改进的混沌调制方案——调幅调频正交混沌键控技术（AF-QCSK）。并对其误码率性能和传输速率进行仿真，结果表明这种改进的调试方案明显提高了系统的通信效率。

| Abstract: | With the development of chaos theory and communication technology, several modulation schemes have been proposed and studied. This paper focuses on modulation and demodulation technology of chaotic communication, and an improved chaotic modulation scheme--Amplitude Frequency Quadrature Chaos Shift Keying is proposed. The BER performance and the data transmission rate of the communication system are simulated. The simulation results show that the efficiency of chaotic communication system is improved significantly. |
