Abstract
A wireless receiver system, for a wireless power transfer system, includes an antenna and a controller, the antenna configured to transmit electrical data signals, the electrical data signals including an encoded message signal. The encoded message signal including one or more encoded message words. The controller is configured to encode one or more message words, of a message signal, into one or more encoded message words of the encoded message signal, based on a coding format. The coding format correlates each of a plurality of correlated ratios with one of a plurality of format words. Each of the plurality of correlated ratios is a ratio of a duty cycle of a pulse to a respective period associated with one or both of the duty cycle and the pulse. Each of the one or more encoded message words are encoded as one of the plurality of correlated ratios.
