    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.

    摘要： A wireless transmission device which communicates with a wireless reception device is provided with a transmission-signal-generating unit configured to generate, transmission signals having transmission rates arranged in order corresponding to an input order of data items of the information sequence. The transmission device is also provided with a preamble adder which adds, to the transmission signals, respective preamble signals assigned in order of the transmission rates and used for estimation of channel responses at the wireless reception device. The transmission device is further provided with transmission units configured to transmit the transmission signals with the preamble signals added thereto.
