Wireless communication technique of reducing influence of an interference signal on a radio signal

A wireless communication system comprising a transmission apparatus, a relay apparatus, and a receiving apparatus,

• wherein
• the relay apparatus includes:
• a first signal receiver that receives a radio first signal transmitted from the transmission apparatus by a plurality of receiving antennas;
• a reception waveform recorder that generates waveform data indicating a waveform of the first signal received by each of the plurality of receiving antennas;
• and
• a second signal transmitter that transmits the waveform data and a second signal indicating a reception time of the first signal to the receiving apparatus, and
• the receiving apparatus includes:
• a second signal receiver that receives the second signal transmitted from the relay apparatus;
• a second signal reception processor that performs reception processing of the second signal received by the second signal receiver to acquire the waveform data;
• a first signal reception processor that performs reception processing of the first signal indicated by the waveform data acquired by the second signal reception processor to acquire data that is set to the first signal by the transmission apparatus;
• and
• a controller that calculates a generation time and a generation position of an interference signal with respect to the first signal on a basis of an observation result of a radio signal in at least one observation apparatus, and instructs the first signal reception processor to perform, in the reception processing, an operation of suppressing an interference signal arriving at the relay apparatus from the generation position at the generation time on the first signal at the reception time corresponding to the generation time.
