    • A transmitter 131 in a communication system 101 receives data to be transferred, performs STBC coding thereon to acquire two signals, performs an OFDM transmission process on the signals which are radio-transmitted to from antennas 141, 142 having polarization polarities orthogonal to each other. A receiver 151 radio-receives the signals using antennas 161, 162 having polarization polarities orthogonal to each other, and performs STBC decoding on two signals acquired by performing an OFDM reception process on the received signals, respectively, thereby acquiring the transferred data. The inclinations of the antenna 141 and the antenna 161 are equal to the inclinations of the antenna 142 and the antenna 162, and are typically 45 degrees.
    • 通信系统101中的发送器131接收要传送的数据,对其进行STBC编码以获取两个信号,对从具有彼此正交的极化极性的天线141,142无线发送的信号执行OFDM发送处理。 接收机151使用具有彼此正交的极化极性的天线161,162进行无线电接收,并对通过对接收到的信号执行OFDM接收处理而获取的两个信号进行STBC解码,从而获取传送的数据。 天线141和天线161的倾斜度等于天线142和天线162的倾斜度,并且通常为45度。
