METHOD, SYSTEM AND APPARATUS FOR SPACE DIVISION MULTIPLE ACCESS AND DATA DEMODULATION

摘要

A method, system and apparatus for space division multiple access and data demodulation are used to divide a plurality of user equipments (UEs) at a base station side and to enhance the data throughput and the data transmission rates of a system. A space division multiple access method for an indoor distribution system includes that the base station receives upstream signals sent from user terminal, and performs the channel estimation according to the upstream signals; the base station performs the antenna belonging judgment to the user terminal according to the result of the channel estimation; the base station classifies the user terminals belonging to the different antennas into a same space division multiple access (SDMA) group and allocates the same radio resources to the user terminals in the SDMA group so as to perform the data transmission.
