    • 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.
    • 无线通信系统包括具有多个发送天线的发送装置和具有多个接收天线的接收装置。 发送装置具有分支单元,其将信号分支为分别通过与发送天线中的每一个对应的多个信号线的多个发送信号,以及设置在至少一个信号线上的延迟单元,以向发送信号施加延迟。 当由分支单元分支的发送信号被延迟单元延迟地应用时,发送装置将施加有延迟的发送信号设置为发送信号,并且经由发送天线将发送信号发送到接收装置 。 接收装置包括延迟单元,其设置在分别通过在接收天线处接收的多个接收信号以对接收信号施加延迟的多个信号线中的至少一个信号线;以及组合单元,其将应用延迟的接收信号设置为 接收信号,并组合接收信号。
