Title:
APPARATUS AND METHOD FOR LOW COMPLEXITY SPATIAL DIVISION MULTIPLE ACCESS IN A MILLIMETER WAVE MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/119039
Kind Code:
A1
Abstract:
A system is configured to perform Spatial Division Multiple Access. The system includes at least one transmitter or receiver capable of polarization alignment. The transmitter includes a baseband precoder configured to precode a signal, an array of sub-array antennas and a plurality of radio frequency (RF) chains. Each RF chain is coupled to a respective antenna sub-array of the array of antennas. The transmitter is configured to perform a method that includes precoding, by a baseband precoder, a signal for spatial division multiple access (SDMA). The method also includes applying, by each of the plurality of radio frequency (RF) chains, a phase shift and beamforming weight to the signal and transmitting the phase shifted and weighted signal by an array of sub-array antennas.
