Abstract:
A radio apparatus comprising:a plurality of antennas provided at different physical positions to receive a radio wave signal, respectively; a plurality of spreading sections provided for said plurality of antennas to spread said radio wave signal received by said plurality of antennas with spreading codes provided for said plurality of antennas to produce spread signals, respectively; a synthesizing section synthesizing said spread signals into an analog synthetic signal; a converting section converting said analog synthetic signal into a digital signal with a frequency such that a digital process can be applied to said digital signal; a plurality of inverse spreading sections provided for said plurality of antennas, to inversely spread said digital signal with inverse spreading codes provided for said plurality of antennas to produce inversely spread signals; and a control unit controlling orientation of said plurality of antennas based on said inversely spread signals.
