    • This publication discloses an RFDD reading apparatus (1) and a method for the reading apparatus. The RFID reading apparatus comprises a transmitter (3), which is arranged to feed power to at least one RFED tag (2) in the vicinity of the RFID reading apparatus (1), and a receiver (4) operating on the frequency of the transmitter (3), so that the transmitter (3) and the receiver (4) are in operation simultaneously and the receiver (4) is arranged to receiver through a radio channel (7) a reflected signal of at least one RFDD tag (2) in the vicinity of the reading device. In accordance with the invention, the RFDD reading apparatus (1) comprises additionally means (Z2, 12, 13, 14, 20) for separating the payload signal arriving from the RFDD tag (2) from signals other than those arriving from the RFDD tag (2).
    • 该出版物公开了一种RFDD读取装置(1)及其读取装置的方法。 RFID读取装置包括发射器(3),其被布置成将功率馈送到RFID读取装置(1)附近的至少一个RFED标签(2);以及接收器(4),其以 发射机(3),使得发射机(3)和接收机(4)同时工作,并且通过无线电信道(7)将接收机(4)布置成接收机至少一个RFDD标签(2)的反射信号 )在读取装置附近。 根据本发明,RFDD读取装置(1)还包括用于将从RFDD标签(2)到达的有效负载信号与从RFDD标签到达的信号之外的信号分离的装置(Z2,12,13,14,20) (2)。
