Abstract
In accordance with an embodiment, a method includes: transmitting, by a first near-field communication (NFC) device, a field emission burst; comparing a characteristic property of a signal of the field emission burst to a detection threshold; determining a presence of a detection error based on the comparing; and adjusting the detection threshold based on a number of determined detection errors.
