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.

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.
