BASE STATION DEVICE AND ARRIVAL DIRECTION DEDUCING METHOD

摘要

Rake synthesizing units (104-1 to 104-n) combine signals having arrived through first to m-th paths for each antenna and create signals each containing components representing the phase rotations between antennas. An arrival direction deducing unit (105) determines one angle spectrum from the signals from the rake synthesizing units (104-1 to 104-n) and determines the positions of the peaks of the angle spectrum to deduce all the arrival directions at a time.
