RADIO COMMUNICATION SYSTEM, TRANSMISSION DEVICE, RECEPTION DEVICE, RADIO COMMUNICATION METHOD, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

A radio communication system is provided with a transmission device for transmitting a plurality of radio signals and a reception device for receiving the plurality of radio signals from the transmission device and estimating the difference between the carrier frequency transmitted by the transmission device and the reference reception frequency used for the reception as a carrier frequency offset. The radio communication system is provided with the transmission device for branching a predetermined first sequence of training signals and transmitting each of the radio signals modulated at the frequency of the carrier frequency offset having the regularity with respect to each of the first sequence of a plurality of the training signals branched and the reception device for estimating the carrier frequency offset with the transmission device according to the amount of phase transition obtained from a first sequence of training signals included in the radio signals transmitted from the transmission device and the predetermined first sequence of training signals.
