1. A radio communication system comprising:

  • a receiver; and

    a transmitter configured to periodically transmit a radio signal for information transmission including information to be notified to the receiver;

    wherein the receiver includesa plurality of antennas;

    a composite signal generation unit configured to generate a composite signal by multiplying a signal output from each antenna when receiving the radio signal for information transmission by a weighting factor for the each antenna to combine the resulting signals from the respective antennas each having been applied with the weighting factor;

    a reception processing unit configured to identify information included in the radio signal for information transmission based on the composite signal generated by the composite signal generation unit; and

    a weighting factor generation unit configured to generate the weighting factor for each antenna that is used for the composite signal generation unit to generate the composite signal, wherein the weighting factor generation unit generates the weighting factor for each antenna based on a plurality of signals output from the plurality of antennas during a period in which the transmitter does not transmit the radio signal for information transmission such that a composite signal obtained by combining signals each resulting from multiplying each of the plurality of signals by the corresponding weighting factor is minimized.
