Abstract
A relay node simulator that outputs a test signal obtained by simulating a signal in which a first RF signal from a base station and a second RF signal transmitted to a mobile communication terminal by a relay node receiving the first RF signal are multiplexed, the relay node simulator including a relay processing unit that generates a second baseband signal on the basis of a first baseband signal, a delay processing unit that provides a predetermined delay to the second baseband signal, a gain adjustment unit that changes a level of the first baseband signal, an adder that adds the first baseband signal and the second baseband signal, and a transmission unit that converts an added signal into an RF signal and transmits a converted signal as the test signal.
