Data communication apparatus and data communication method

摘要

According to the embodiments of the application, the data communication apparatus is provided by comprising plural antennas 101, the first to n-th antenna synthesis receivers 701a to 701e for dividing received signals provided via plural antenna 101 according to the incoming time, calculating weights for the divided radio signal to synthesize the received signals provided via plural antennas 101, and multiplying the received signals provided via plural antennas 101 by the calculated weights to synthesize; and a profile estimator 707, in the case where a new radio signal is detected, for updating the weights to synthesize the newly detected radio signal using the weights already calculated in the first to n-th antenna synthesis receivers 701a to 501e when an incoming time difference between an already detected radio signal and the newly detected radio signal is small.
