| Abstract: | The denoising problem of impure chaotic signals is
addressed in this paper. A method based on sparse representation is
proposed, in which the random frame dictionary is generated by a
chaotic random search algorithm. The numerical simulation shows the
proposed algorithm outperforms those recently reported alternative
denoising methods. |
