Abstract :
An enhanced chaos shift keying named FM-QACSK (Frequency Modulated Quadratrue Amplitude chaos shift keying) is presented in this paper by using a high-level signal constellation in the FM-QCSK (Frequency Modulated Quadratrue chaos shift keying) system This scheme improves the speed of chaos shift keying and its noise performance is better than other chaotic communication systems, such as DCSK and QCSK.
