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。
With the development of chaos theory and communication technology, the performance of various communication modulation schemes has gradually been researched and mastered by people. In this paper, an improved chaotic modulation scheme called AF-QCSK is proposed by analyzing and researching the existing chaotic modulation and demodulation methods, combining amplitude modulation, frequency modulation and quadrature. The performance of the BER and the transmission rate are simulated. The results show that the improved debugging scheme obviously improves the communication efficiency of the system.
