Document Type and Number:
Japanese Patent JP3574055
Kind Code:
B2
Abstract:
A wireless base station comprises a response vector calculation unit (561), an RSSI measuring unit (562), an MSE calculation unit (563), an FD calculation unit (564) and the like, and those units obtain an index showing communication quality of at least one of two mobile stations that are intended to be space-division multiplexed. According to the index, a control unit (80) judges the suitability of the two mobile stations for space-division multiplexing and performs space-division multiple access communication when judging suitable. The effect achieved with this construction is that the wireless base station maintains quality of communication between the wireless base station and mobile stations at a certain satisfactory level when performing space-division multiple access communication.
