Abstract
A wireless medical signal processing system for health monitoring is disclosed which achieves high wireless link reliability/security, low power dissipation, compactness, low cost and supports a variety of sensors for various physiological parameters. The system includes a medical signal processor which communicates with a wireless distributed sensor system as its peripheral for detecting physiological parameters of the person and for providing signals indicative thereof. The medical signal processor wirelessly receives the signals from the distributed wireless sensor system in a multiplexed fashion and processes the signals to provide an indication of the health of the person. The indication of health could relate to a disease state, general health or fitness level of a person. The system also includes a mobile device for receiving the indication of the health of the person to allow for a diagnosis or treatment of the person.
