1. A wireless communication system including a wireless communication terminal that communicates with a base station at a frequency in a white space, the wireless communication terminal comprising:

  • an array antenna;

    a MAC processing section provided to detect a first order system, the MAC processing section interpreting information on a quiet period that the base station has informed of the MAC processing section in advance, and generating a quiet period signal;

    a synthesizing section weighting signals received from antennas of the array antenna by using weighting coefficients, and combining the signals to produce a synthetic signal; and

    an array antenna control section optimizing the weighting coefficients so as to reduce an interference signal received by the array antenna, over a period of presence of the quiet period signal.
