PURPOSE: A co-channel relay device using a multi receiving antenna and a method thereof are provided to efficiently combine DMB signals received by using receiving antennas of a co-channel relay by using a maximal ratio combining method. CONSTITUTION: Each of first and second weighted value applying units (241,243) multiplies a maximal ratio combining (MRC) weighted value by broadcasting signals received from each receiving antenna. A signal combining unit (250) combines broadcasting signals multiplied by the MRC weighted value. An afterimage signal processing unit (260) processes an afterimage signal generated from the signals outputted by the signal combining unit. A transmitting unit (270) transmits the broadcasting signals processed on the afterimage signal through a transmission antenna by using a frequency band.
