摘要
给出一种基于FM DCSK(调频 差分混沌移位键控)的非同步解调方法,利用码元位置匹配的思想解决了解调过程中的同步问题,降低了系统要求.在加入一定均匀噪声的情况下,仍解调出原始位信息.仿真结果表明该方法有效可行.
This paper presents and asynchronous demodulation method based on FM-DCSK and solves the synchronous problem is demodulation by matching of th code element position, which lowers the system requirement. The method can demodulate original information even if some noise is added to the system. Compared with the demodulation results of ideal synchronization, the simulation results prove the efficiency and practicality of this method.
