Maximum likelihood approaches for noncoherent communications with chaotic carriers

This paper deals with two problems. The first one is the noise decontamination of chaotic carriers using a maximum likelihood approach, the second is the design of communications schemes with chaotic carriers. After presenting improvements of the noise decontamination algorithms, we apply them in communication schemes. Experimental evidences show competitive capabilities of the proposed schemes with respect to the existing chaos-based modulation-demodulation techniques. In our approach we assume that the dynamics of the carriers are known in advance.
