PURPOSE: A digital on-channel relay using minimum mean square error method is provided to efficiently remove interferential signal while taking diversity gain using a plurality of antennas. CONSTITUTION: A receiving unit(420) receives broadcasting signal of a predetermined frequency band through a plurality of reception antenna from a broadcasting signal transmission unit. A weighted value calculation unit(450) calculates MMSE(Minimum Mean Square Error) weighted value about each reception antenna. A complex filter(460) multiplies the calculated MMSE weighted value to the received broadcasting signal. A transmitting unit(470) combines the outputs of the complex filters about each reception antenna. |
