Abstract:

A transceiver system comprises transceivers and a controller in communication with the transceivers. Each of the transceivers comprises an emitter, a receiver operatively connected to the emitter, a primary data path operatively connected to the receiver, a secondary data path operatively connected to the receiver, a statistical unit operatively connected to the secondary data path and the controller and a display device operatively connected to the primary data path. The controller determines relative positions of the transceivers, and the statistical unit infers characteristics of the transceivers, forms a composite received signal model for all of the transceivers based on the relative positions and the characteristics, computes an electromagnetic interference likelihood value for a transceiver of the transceivers and identifies whether the transceiver is a source of electromagnetic interference by determining whether the electromagnetic interference likelihood value of the transceiver exceeds a threshold value.
