Abstract

According to one embodiment, a method for communication includes receiving, by a receiver, a first modulated signal. The first modulated signal includes at least one error. The method also includes demodulating the first modulated signal. The demodulation includes compensating for the at least one error utilizing information related to a velocity of the receiver.
