Abstract
A wireless receiver system includes a receiver antenna, a sensor, a demodulation circuit, and a receiver controller. The sensor is configured to detect electrical information associated with AC wireless signals, the electrical information including, at least, a voltage of the AC wireless signals. The demodulation circuit is configured to receive the electrical information from the at least one sensor, detect a change in the electrical information, determine if the change in the electrical information meets or exceeds one of a rise threshold or a fall threshold, if the change exceeds one of the rise threshold or the fall threshold, generate an alert, and output a plurality of data alerts. The receiver controller is configured to receive the plurality of data alerts from the demodulation circuit, and decode the plurality of data alerts into the wireless data signals.
