    • Outputs of A/D converters 110, 111, and 112 are input to correlation devices 117, 118, and 119. The correlation devices 117, 118, and 119 output ratios of these signals to an output signal of a modulator 116 for modulating an output of a switching device 115. Each of standardizing devices 120, 121, and 122 cancels a gain component from an input signal, and selects a signal having a maximum signal-to-interference power ratio. A switching device 124 switches a transmitting antenna in accordance with the selection result so as tc send a transmitting message. A switching device 125 switches a unique word in a synchronous burst, and a unique word in a communication channel signal, or a receiving message to be sent to the correlation devices as a reference signal.

    • A complex multiplying section multiplies a receiving signal by a complex weighting factor of a weighting factor controlling section. The output is added by an adding circuit, and decoded by a decoding circuit so as to obtain a received signal. The weighting factor of the weighting factor controlling section is set using only the weighting factor calculated by a synchronous burst having a different unique word pattern. On one hand, it is assumed that an interference station having the same unique word pattern exists. Then, a decision feedback adaptive array antenna receiving circuit 400, which does not update the weighting factor using the unique word pattern, performs a signal reception. On the other hand, it is assumed that no interference station having the same unique word pattern exists. Then, the conventional decision feedback adaptive array antenna receiving circuit 500, which updates the weighting factor using the unique word pattern, performs a signal reception. Thereafter, a correct signal is selected from either one of the circuits. Thereby, the complex weighting factor of the adaptive array antenna is appropriately updated, so that a received signal can be extracted from the desired signal.
    • 复乘单元将接收信号乘以加权因子控制部分的复加权因子。 输出由加法电路相加,由解码电路进行解码,得到接收信号。 加权因子控制部分的权重因子仅使用由具有不同唯一字模式的同步脉冲串计算的加权因子来设定。 一方面,假设存在具有相同唯一字模式的干扰站。 然后,不使用唯一字模式更新加权因子的判定反馈自适应阵列天线接收电路400执行信号接收。 另一方面,假设不存在具有相同唯一字模式的干扰站。 然后,传统的判决反馈自适应阵列天线接收电路500使用唯一字模式更新加权因子,执行信号接收。 此后,从任何一个电路中选择正确的信号。 因此,自适应阵列天线的复加权因子被适当地更新,从而可以从期望的信号中提取接收的信号。
