Method and device for calibrating smart antenna array

摘要: This invention discloses a method and device for calibrating smart antenna arrays in real time. The includes the steps of providing link comprising coupling structure, feeder cables pilot transceiver; pre-calibrating structure with vector network analyzer recording its receiving transmitting transmission coefficients, respectively; implementing calibration to array by adjusting coefficient each reference same amplitude phase difference Φ, which is recorded stored baseband processor; Ψ, processor. implemented using spatial couple mode or passive network.
