摘要： A wireless communication device (1) comprises a spatially-multiplexed PSC extracting section (8) for extracting a spatially multiplexed known pilot subcarrier signal (S5) from the received multicarrier-modulated signal, a reference signal generating section (7) for generating a reference signal (S4) of the spatially-multiplexed pilot subcarrier signal, and a phase compensating section (9) for compensating the phase difference of the received signal (S1) according to the pilot subcarrier signal (S5) extracted by the spatially-multiplexed pilot subcarrier extracting section (8) and the reference signal (S4). Therefore, even if a pilot subcarrier signal is spatially multiplexed and transmitted, phase difference detection and phase compensation can be performed by a simple constitution.

摘要： A reception device includes reception antennas and an address generation unit that converts a write-in or read-out order of channel estimation values according to a rearrangement rule. A storage unit writes in or reads out channel estimation values in the converted order, and an address generation unit converts a data sequence write-in or read-out order according to the rearrangement rule. A signal storage unit writes in or reads out data sequences in the converted order, and a replica generation unit generates a replica signal by re-modulating the data sequence according to the channel estimation value. A cancel unit successively generates a stream signal in which a data sequence interference signal is cancelled, by using the channel estimation value, the data sequence, and the replica signal.

摘要： A wireless base station device includes a plurality of transmit weight generation sections and a beam selection section. The transmit weight generation sections generate pieces of transmit weight information used for spatial division multiplexing transmission according to different algorithms. The pieces of transmit weight information are generated based on channel information on a plurality of terminals each having one or more antennas with which the wireless base station device performs spatial division multiplexing transmission. The beam selection section selects one of the pieces of transmit weight information generated.

摘要： A spatial filtering adaptable for an interference wave that appears unsteadily can be implemented and also an interference canceling ability can be increased even in a condition that the interference wave does not steadily exist. At a time of non-active communication, the signals from a plurality of interference source radio communication devices 2 are received in advance by an interference signal receiving section 6 as the pre-process mode, then a resultant interference correlation matrix RI is stored in a storing section 7, and then an interference wave receiving antenna weight WI used to receive selectively the transmission signals from the interference source radio communication devices 2 is prepared based on the resultant interference correlation matrix RI. At a time of communication, the operation goes to the receiving process mode to normally receive the signal by a signal separating section 9, and a variation of the interference wave component is detected by an interference wave level detecting section 8 based on a signal power received using the interference wave receiving antenna weight WI. When the interference wave appears or changes, a desired wave separating/receiving antenna weight used to reduce the interference by using a new interference correlation matrix is changed adaptively.
