<p>PURPOSE: A signal repeater in a communication system and a method thereof are provided to relay signals by minimizing an interference signal in a relay process of a signal transmitted and received between a transmitter and a receiver. CONSTITUTION: A reception antenna(110) receives an input signal received from a transmitter. A power amplification unit(140) amplifies the input signal into a predetermined level. Transmission antennas(150) transmit the amplified input signal to a receiver. Self-interference generated by the amplified input signal transmitted through the transmission antennas is eliminated by an SDIN(Spatial-Domain Interference Nulling) method, and the reception antennas receive the input signal.
