    • The invention is directed to the reception of high rate radio signals (for example DVB-T signals) while the receiver is moving at a high speed (for example in or with a car). Two or more antennas (12, 16) are closely spaced and arranged behind each other in the direction of motion (v) for receiving the radio signals. A signal is obtained which represents a virtual antenna (26) that is at least temporarily stationary with respect to the environment, despite the movement of the receiver. The receiving signal of the virtual antenna (26) suffers at least less distortions than a signal received by one of the first and second antennas (12, 16). In accordance with the invention the signal which represents the virtual antenna (26) is obtained under the control of a feedback signal (SYNC) of the receiver.
    • 本发明涉及在接收机高速移动(例如在汽车中或与汽车相关)时接收高速无线电信号(例如DVB-T信号)。 两个或多个天线(12,16)在运动方向(v)之间彼此紧密地间隔开并布置成用于接收无线电信号。 获得信号,其表示虚拟天线(26),其相对于环境至少暂时静止,尽管接收机的移动。 虚拟天线(26)的接收信号比由第一和第二天线(12,16)中的一个接收的信号遭受至少更小的失真。 根据本发明,在接收机的反馈信号(SYNC)的控制下获得表示虚拟天线(26)的信号。
