Abstract: PURPOSE: A spatial division multiple access (SDMA) apparatus of low complexity in a millimeter wave mobile communication system and a method thereof are provided to implement SDMA of low complexity in the millimeter wave communication system. CONSTITUTION: A digital baseband precoder precodes a signal. A plurality of radio frequency (RF) chains applies phase shift and beamforming weighted value to the signal. Each RF chain is combined to each antenna sub array of an array. The digital baseband precoder includes a digital precoder. The digital precoder applies a digital beamforming weighted value to the signal.
