TRANSMITTING AND RECEIVING APPARATUS IN ADAPTIVE ARRAY ANTENNA SYSTEM CAPABLE OF REALTIME ERROR CALIBRATION AND METHOD THEREOF

摘要

The present invention relates to a transmitting and receiving apparatus and method of the adaptive array antenna system with a real-time error correction. The transfer function of the transmission and reception device is estimated by the method of injecting the error correction signal for every transmission channel, and analyze the signal after the signal has passed through the transmit and receive channels. At this time, by using the RF signal to an intermediate frequency tone error correction signal it may be a process of signal processing in the baseband simplified. Moreover, all the channels received relative transmission gain function characteristic by controlling a single channel signal received by the apparatus in the error correction at the receiving device is constant regardless of the gain of the receiver. This is to increase the error correction coefficient update cycle the error correction signal reduces the effects of interference on the transmission and reception device. ; Smart antennas, adaptive array antenna systems, a real-time error correction, the intermediate frequency tones, the beamforming, the transfer function, AGC
