Abstract
A method and apparatus for wirelessly transmitting data between two devices () is provided herein. During data transmission, a data and a strobe signal are transmitted simultaneously on the I and Q-channels, respectively, of over-the-air interface. More particularly, QPSK modulation is utilized, with the strobe signal being transmitted via the I-channel, and the data signal being transmitted via the Q channel, (or vice versa). Additionally, illegal constellation transitions are utilized to signal the transmission of control information.
