COMMUNICATION APPARATUS AND COMMUNICATION SYSTEM

摘要

A propagation estimating part (103) uses a reference signal of propagation estimation, sent from the other end of communication, to estimate a propagation environment. This estimation result is sent, as propagation information for reception/demodulation parameters, to a receiving part (102) and a demodulating part (104), thereby removing multipath components from a received signal or performing phase adjustment and the like, in accordance with the propagation information, to output demodulated information.
