A digital unit, a signal processing system, and a signal processing method are disclosed. The signal processing system includes a digital unit and a plurality of radio units. The digital unit is connected to a core system and configured to process radio digital signals. The plurality of radio units are physically isolated from the digital unit and configured to convert and amplify digital signals received from the digital unit, to transmit the amplified signals to a terminal based on a multi-antenna technology using two antennas, and to receive the signals from the terminal and to transmit the same to the digital unit based on the multi-antenna technology using two antennas, If a first cell is adjacent to a second cell and if the first cell and the second cell are configured to use the same reference signal, a radio unit of the first cell and a radio unit of the second cell use the same resource element to transmit the same data to a terminal located in a boundary region of the first and second cells. |
