Title:
WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION SYSTEM AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2010/146774
Kind Code:
A1
Abstract:
A wireless communication apparatus comprises: a propagation path information acquiring unit for acquiring, based on received signals, both a transmitted signal propagation path matrix, which is the propagation path information of the transmitted signals of a before-interference-removal transmitted signal group, and an interference signal propagation path matrix, which is the propagation path information of the interference signals of a non-interference-removal transmitted signal group; an interference signal calculating unit for generating, based on the before-interference-removal transmitted signal group, non-interference-removal transmitted signal group, transmitted signal propagation path matrix and interference signal propagation path matrix, an interference signal group of the before-interference-removal transmitted signal group that is present during reception and that is caused by the non-interference-removal transmitted signal group; an interference signal subtracting unit for subtracting the interference signal group from the before-interference-removal transmitted signal group to generate an after-interference-removal transmitted signal group; and a transmission antenna group for transmitting the after-interference-removal transmitted signal group and non-interference-removal transmitted signal group via different transmission antennas.
