A set of stators of a linear induction motor are mounted on a track. A three-phase current is provided to each of the stators, such that a traveling magnetic field (TMF) is created by the stators along the length of the track. The traveling magnetic field includes a magnetic flux corresponding to a stator excitation modulated with a message signal. A rotor includes a series of conductor plates. As the traveling magnetic field passes through the conductor plates, a current is induced in the plates by induction. Such current then generates an opposing magnetic field causing the plates and the vehicle to be propelled. Each phase may first be modulated with a message signal, before being provided to the stator. The current at the rotor is then demodulated to realize the message signal. A doppler shift due to the speed of the rotor relative to the stator is corrected.
