The multi-stage chaotic secure communication system applied in Radio Frequency channel
In this paper a multi-stage chaotic secure communication system applied in radio frequency( RF) channel is proposed. This scheme adopts multi--stage chaotic asynchronous cascades in order to improve the traditional chaotic masking method which is tended to be broken the security can be enhanced obviously. The systematic structure of the receiver can be simplified by the two parallel driving signals are transmitted to the receiver simultaneously after implementing quadrative amplitude modulation(QAM) .The numerical simulation shows this scheme with simple system design can obtain better security and it also can be applied in the wireless communication field.
