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 transmission 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.
Las aplicaciones de la teoría del caos en ramas como las comunicaciones, la telemedicina y el procesamiento de señales e imágenes, son cada vez más frecuentes. Los algoritmos que generan señales caóticas pueden ser utilizados para la generación de portadoras, la encriptación y la codificación, entre otras aplicaciones. En este trabajo se plantea un método de transmisión que permite combinar señales electrocardiográficas (ECG) obtenidas de un paciente, con algoritmos que generan señales caóticas utilizando como base el sistema de ecuaciones de Lorenz. En este proceso se obtienen resultados aceptables frente al ruido y otros métodos de modulaciones tradicionales.
