Abstract

Certain aspects and embodiments are directed to a Doppler shift correction sub-system that can be disposed in a mobile repeater. The Doppler shift correction sub-system can include a processor and a frequency-shifting module. The processor can be configured to determine a corrective frequency shift based on a velocity of the repeater relative to a source and a representative transmission frequency. The processor can provide the corrective frequency shift to a frequency-shifting module. The frequency-shifting module can be configured to shift the signal using the corrective frequency shift prior to transmitting the signal to a destination, such as a mobile device.
