Abstract :
This paper proposes an automatic calibration method that can be applied to frequency division duplex (FDD) systems. The effectiveness of the proposed calibration method is evaluated by measurements using an adaptive array testbed in an anechoic chamber. This paper first elucidates the required calibration for FDD systems. Then the proposed calibration method is described. Finally, the measurement results are shown.
