APPARATUS AND A METHOD FOR UPLINK BEAM FORMING AND SPACE-DIVISION MULTIPLE ACCESS IN A MULTI-INPUT MULTI-OUTPUT WIRELESS COMMUNICATION SYSTEM, CAPABLE OF MAXIMIZING UPLINK SIGNAL TRANSMISSION CAPACITY

摘要

PURPOSE: An apparatus and a method for uplink beam forming and space-division multiple access in a multi-input multi-output wireless communication system are provided to form a beam, thereby maximizing an SINR(Signal to Interference Noise Ratio).;CONSTITUTION: An apparatus for uplink beam forming and space-division multiple access in a multi-input multi-output wireless communication system includes a generator, one transmission RF chain(116), an RF switch(117), and beam formers(118). The generator generates an uplink signal. The transmission RF chain converts a baseband signal from the generator to a signal of an RF band. The RF switch switches an RF signal from the transmission RF chain to one among the beam formers. One of the beam former multiplies the RF signal from the RF switch with a corresponding weight vector and transmits it through antennas(101,102,103).;COPYRIGHT KIPO 2010
