Abstract
A communication interference rejection system comprising a receiver operatively connected to a device connected to a body of a user. The receiver is configured to receive a signal transmitted through the body of the user, the signal comprising a data component and an interference component, the interference component due to human body antenna effect. The receiver is configured to integrate the signal using a relatively low-gain analog integrator and then digitally differentiate the output of said integration.
Claims5
A communication interference rejection system comprising:
- a receiver operatively connected to a device connected to a body of a user, the receiver configured to receive a signal transmitted through the body of the user, the signal comprising a data component and an interference component, said interference component due to human body antenna effect, said receiver comprising a relatively low-gain analog integrator and a differentiator, wherein the analog integrator integrates the signal and then the differentiator digitally differentiates the output of said integration.
A communication interference rejection system comprising:
- a receiver operatively connected to a device connected to a body of a user, the receiver configured to receive a signal transmitted through the body of the user, the signal comprising a data component and an interference component, said interference component due to human body antenna effect, said receiver configured to integrate the signal using a relatively high-gain analog integrator wherein the output of said integrator saturates to a rail-to-rail voltage to allow the receiver to decode the signal received from said integrator using a serial protocol.
