A method for calibrating smart antenna array systems in real time

The invention is a device for real-time calibration to the intelligent antenna array by using the same. The antenna array is mounted on the pre-calibration to obtain the antenna according to calibrate the transmitting and receiving compensation of coefficient antenna unit relatively. The antenna array is mounted, wherein a correction, composed of a link simultaneous a calibrating signals, a base band signal processor correcting to the signal of the link receiving calculates, wherein the transmission and amplitude phase response information, a preparatory from a point-shaped compensation coefficient together, the computer obtaining the transmission links' compensation coefficients, a base station downlink data, compensationMethod for correcting, a correction ring and calibrating signal, a base band signal processor automatically according to the signal with multiple receiving chains; and calculates each receiving chain and amplitude phase response information, a preparatory from point-shaped receiving compensation coefficient together, the computer obtaining the receiving chains' compensation coefficients, a base station uplink data compensation. The antenna units' calibrating signals of a calibrated the sequence substantially comprising a cycle of movement of forming.
