Claim:
1. A system to enable both wireless power transfer and data communication by use of a same transmit signal to one or more mobile devices, the system comprising: a constraint encoder that is configured to receive data bits for communication to the one or more mobile devices and to encode the data bits onto a transmit signal; the constraint encoder further configured to specify, based on the received data bits, one or more signal constraints that change frequency, phase, or amplitude components of the transmit signal to cause the transmit signal to have at least a specified peak-to-power-average ratio (PAPR) during a given time interval sufficient to provide the wireless power transfer to the one or more mobile devices, wherein the specified one or more signal constraints are selected to maintain the specified PAPR during the given time interval; a signal generator coupled to the constraint encoder and configured to generate the transmit signal according to the one or more signal constraints; and a transmitter coil that is coupled to the signal generator and is configured to transmit the transmit signal that has been encoded with the data bits to one or more receiver coils of the one or more mobile devices, the encoded transmit signal able to provide the wireless power transfer and the encoded data bits to the one or more mobile devices.
