Noise-like waveform and strange attractor are considered as important characteristics of chaos. In this paper, a new chaotic system with a novel attractor looking like limit cycle, which generates a sine-like output waveform, is found. The existence of chaotic signal with sine-like waveform is further investigated by employing several numerical tools and verified by simulating an experimental circuit.
In this paper, we address the problem of blind extraction and separation of a continuous chaotic signal from a linear mixture consisting of some chaotic signal and/or random signals. The problem of blind extraction is firstly formulated as a problem of the synchronization-based parameter estimation. Then an efficient least square based parameter estimation method is introduced to determine the desired...
