摘要： A wireless communication system includes a transmission device including plural transmission antennas and a receiving device including plural reception antennas. The transmission device includes a branching unit that branches a signal into plural transmission signals respectively passing plural signal lines each corresponding to each of the transmission antennas and delay units provided on at least one of the signal lines to apply a delay to the transmission signal. When a transmission signal branched by the branching unit is applied with a delay by the delay units, the transmission device sets the transmission signal on which the delay is applied as the transmission signal, and transmits the transmission signals to the receiving device via the transmission antennas. The receiving device includes delay units provided on at least one of plural signal lines that respectively pass plural reception signals received at the reception antennas to apply a delay to the reception signal and a combining unit that sets the reception signal on which the delay is applied as the reception signal, and combines the reception signals.

摘要： A communication apparatus constitutes a wireless communication system with a base station and a terminal station, and relays and transfers a signal transmitted and received between the base station and the terminal station. The communication apparatus uses a frequency different from that at a time of reception to amplify and transfer the received signal, when having received a signal transmitted from the base station or the terminal station.
