ABSTRACT:
Disclosed is a transceiver for a base station with a smart antenna having a plurality of antennas. The transceiver comprises: a multipath searching unit for searching multipath delay information for each demodulation channel; a demodulating unit for forming an adaptive beam for each demodulation channel by using the multipath delay information for each demodulation channel for receiving signals and performing demodulation to the received signals and outputting at least one adaptive beam weight vector; a controlling unit for selecting at least one downlink beam index for each channel; and a modulating unit for selecting the downlink switched beams and forming switching beam for modulating signals of each channel and outputting the modulated signals in downlink.
