发明名称 Apparatus and method for correcting doppler shift in mobile communication systems
摘要 A system and method for correcting for Doppler shift in transmitted and received electromagnetic wave, light wave, or acoustic wave signals between two platforms, where at least one of the platforms is moving relative to the other. The system involves determining a Doppler shift that affects the frequency of a signal being transmitted from a transmitting platform, as a result of motion of the transmitting platform, and adjusting the frequency of the transmitted signal to cancel out the determined degree of Doppler shift that will be experienced by the receiving platform. If the receiving platform is also moving, then a determination is made as to the Doppler shift that will be imparted to the signal being received because of motion of the receiving platform. A receiver on the receiving platform is controlled to account for this degree of Doppler shift. Therefore, the Doppler shift components attributable to the motion of each, or both, platforms is accounted for.
