Abstract
A wireless communication system for a moving vehicle, and a method of operation of a wireless communication system for a moving vehicle, are described. The wireless communication system comprises an antenna system configured to receive a received signal from a further antenna system and to transmit a transmitted signal to the further antenna system, communication control circuitry to control operation of the antenna system, and analysis circuitry. The analysis circuitry is configured to obtain at least one item of information from the received signal, and perform a Doppler adjustment process to determine, based on the at least one item of information, an adjusted transmitted frequency (f) to be used for transmission of the transmitted signal from the antenna system, such that an observed frequency of the transmitted signal at the further antenna system is a predetermined uplink frequency (f).
