Abstract
A wireless power system has a wireless power transmitting device and a wireless power receiving device. The devices in the wireless power system may communicate using in-band communication. The wireless power transmitting device may transmit data to the wireless power receiving device using frequency-shift keying (FSK) modulation. The receiving device may not be aware of the transmission rate of the FSK data. The FSK decoder may identify an actual transmission rate of the incoming bits and decode the wireless power signals into subsequent bits using the actual transmission rate.
