摘要

Biosignals such as Electrocardiogram (ECG), Electroencephalogram (EEG) and Electromyogram (EMG) contains critical and sensitive information about the patient's health. In order to preserve its confidentiality, the information about the patient must be transmitted in a secure manner. In this work, biosignals are communicated by employing a chaotic secure system to safeguard the medical information. Chaotic signals are generated using the nonlinear components of Chua circuit. Chaos theory portrays nonlinear dynamics of a system, in which random events are actually predictable from simple deterministic equations. Transmitter and receiver are synchronized using bidirectional coupling. Time division multiplexing (TDM) method is adopted for transmitting different Biosignal at a time in an efficient manner by reducing the intersymbol interference and signal loss. Multisim.13 software is used to simulate chaotic communication system and ECG signals for transmission. In the receiver end, band pass filter with a pass — band frequency of 0.05–100Hz is employed to remove the noise. From the results, ECG signal transmitted was recovered with less deterioration and can be efficiently used for diagnosis.
