BARBARA, E; ALBA, E  and  RODRIGUEZ, O. Modulating electrocardiographic signals with chaotic algorithms. Ing. Investig. [online]. 2012, vol.32, n.2, pp.46-50. ISSN 0120-5609.

Chaos theory is becoming increasingly applied to areas like communications, telemedicine and processing signals and images. Algorithms generating chaotic signals can be used for generating, encrypting and encoding carriers. This work proposes a transmis-sion method allowing electrocardiogram (ECG) signals obtained from a patient to be combined with algorithms generating chaotic signals, based on the Lorenz equation system. Acceptable results were obtained regarding noise and other traditional modulation methods.

Keywords : algorithm; chaotic signal; ECG signal.
