    • A receiver includes two reception antennas, which receive a modulated wave (transmission signal) from each of transmitters, a selection circuit, which alternately selects one of the two reception antennas at a predetermined switching cycle to alternately obtain the modulated wave from the two reception antennas, and a demodulation section, which generates a demodulated signal by demodulating the modulated wave obtained at the selection circuit. The switching cycle is 27 μs, which is 1/7.4 of the transmission time of data per symbol in the transmission signal from each transmitter, that is, 200 μs. In other words, the modulated waves from the two reception antennas are alternately obtained at least seven times each while the data of one symbol is transmitted.
    • 接收机包括两个接收天线,其接收来自每个发射机的调制波(发射信号),选择电路,以选定的切换周期交替地选择两个接收天线中的一个,以交替地从两个接收天线获得调制波 以及解调部,其通过解调在选择电路处获得的调制波来生成解调信号。 开关周期为27μs,这是来自每个发射机的发送信号中的每个符号的数据的传输时间的1 / 7.4,即200μs。 换句话说,来自两个接收天线的调制波在发送一个符号的数据的同时交替获得至少七次。
