DEVICE FOR BEAM-FORMING A SIGNAL IN A MULTI USER-MULTI ANTENNA WIRELESS COMMUNICATION SYSTEM, CAPABLE OF DETECTING TRANSCEIVING BEAM-FORMING VECTOR ONLY BY CALCULATION OF A NUMERICAL ANALYSIS
PURPOSE: A device and a method for beam-forming a signal in a multi user-multi antenna wireless communication system are provided to rapidly generate transceiving beam-forming vector, thereby obtaining decrease of delay in a signal transmission and improvement of system stability.;CONSTITUTION: A combination unit(303) performs receive beam-forming process by a receive signal, a channel state information matrix and a beam-forming vector. The combination unit filters a signal transmitted to a relevant terminal. A combination unit controller(302) extracts a transmission beam-forming vector in a pilot signal transmitted from a based station. A demodulator(305) generates encoded data bit by demodulation of the filtered signal. A channel decoder(306) approximates a transmission signal by demodulation of the encoded data bit.;COPYRIGHT KIPO 2011
