1. A relay station capable of executing non-regenerative relay of a first radio signal transmitted from a transmission station to a reception station having one antenna, the relay station comprising:
a plurality of antennas;
a plurality of wireless devices corresponding to the plurality of antennas, respectively; and
a controller configured to control an operation of the plurality of wireless devices, wherein
each of the plurality of wireless devices includes
a receiver configured to convert the first radio signal received by a corresponding antenna into a baseband signal;
a finite impulse response (FIR) filter configured to assign a delay to the baseband signal; and
a transmitter configured to convert a signal output from the FIR filter into a second radio signal transmitted from the corresponding antenna to the reception station,
wherein the controller sets a different delay amount in the FIR filter in each of the plurality of wireless devices so that the FIR filter assigns a delay, which is different from among the plurality of antennas, to the baseband signal input from the receiver in each of the plurality of wireless devices.
