ELECTRODE DIVERSITY FOR BODY-COUPLED COMMUNICATION SYSTEMS
First Claim
1. A coupler device for a body-coupled communication, said coupler device being configured to be placed at or in close proximity to a human or animal body and comprising an electrode arrangement consisting of a plurality of electrodes or electrode segments (40, 42;
- 40, 43) adapted to be separately connectable to achieve electrode diversity.

Abstract
The present invention relates to coupler device, processing apparatus and method of processing a plurality of body-coupled communication signals which have been detected by using an electrode arrangement with a plurality of electrodes or electrode segments (40, 42; 40, 43). Respective transmission parameters of the body-coupled communication signals are estimated and at least one of a selecting and weighting processing is applied to the detected body-coupled communication signals based on the estimated transmission parameters. Then, the processed body-coupled communication signals are combined to generate a diversity output signal. Thereby, robustness against coupler misplacement and user convenience is increased in body-coupled or body-based communication systems.
