Abstract

Abstract: This paper presents and asynchronous demodulation method based on FM-DCSK and solves the synchronous problem is demodulation by amtching of the code element position, which lowers the system requirement. The method can demodulate original information evey 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.

Key words: chaos, asynchronization, FM-DCSK, communication simulation
