    摘要: A wireless transmitting device for use in communication with a wireless receiving device with a wireless packet, includes a plurality of antennas, and a signal generator to generate a signal for a wireless packet to be transmitted. The wireless packet includes an automatic gain control (AGC) preamble sequence and data transmitted by using a plurality of subcarries from the plurality of antennas. The AGC preamble sequence includes a frequency component in which a value at a time “t” of a signal in a time domain of the AGC preamble sequence transmitted from an iTx-th antenna (where iTx=1, 2, 3, . . . ) is different for each of the antennas.

    摘要: According to one embodiment, a communication device communicates with N remote units. Each remote unit includes a plurality of antennas, wireless transmitting units, and wireless receiving units. The communication device is provided with a received signal processing unit, to which received signals by a plurality of the wireless receiving units are combined and input, and which specifies the remote unit subjected to interference, and a switch which decreases a reception gain of the wireless receiving unit included in N−1 remote units out of the N remote units in a predetermined measurement section. The received signal processing unit calculates a correlation value between the combined received signals and a reference signal transmitted by a user terminal connected to another base station system in the measurement section and specifies the remote unit subjected to the interference by the second user terminal based on the correlation value.
