BEAMFORMING APPARATUS FOR COMMUNICATION SYSTEM USING MULTI-ANTENNA

摘要

A beamforming device for a communication system using a multi-antenna is disclosed. The present invention can implement a beamforming device combing digital and analog methods by including a plurality of phase controllers corresponding to each of the plurality of D/A converters or A/D converters instead of having a plurality of D/A converters or A/D converters less than the number of antennae. Therefore, the plurality of D/A converters or A/D converts are made to correspond to multiple data streams, and the size and manufacturing costs can be reduced by decreasing the number of D/A converters or A/D converters.
