摘要： Systems and methods for sensing reverse link signaling are described herein. In one aspect, an apparatus for wireless transmission includes a push-pull driver circuit, coil, and sensor. The push-pull driver circuit is configured to generate a signal. The coil is electrically coupled to the push-pull driver circuit, and the coil is configured to receive the signal from the push-pull driver circuit and wirelessly transmit the signal to a receiver. The sensor is electrically coupled to a virtual alternating current (AC) ground of the push-pull driver circuit or the coil. The sensor is configured to sense a shift in voltage at the virtual AC ground where the shift in voltage is representative of a change of an input impedance of the receiver.
