Title: System and method for downlink beamforming using uplink array response vector
Inventor: KYUNG MUN GEON
IPC: H01Q3/38
Filed: 2000-11-16
Abstract: PURPOSE: A down link beam forming system and a method thereof are provided to transmit a maximal power to a direction in which a desired terminal is located using a receiving array response vector obtained in a uplink. CONSTITUTION: An adaptive array modulator(105) generates a reference signal necessary to estimate a receiving array response vector. A correlator(106) estimates the receiving array response vector by obtaining an average with respect to a time of a signal obtained by multiplying the reference signal by digital receiving data. A transmission beam form weight calculator(110) removes an uplink channel component from the receiving array response vector to obtain a receiving antenna response vector. The transmission beam form weight calculator(110) calculates a transmission beam form weight using the receiving antenna response vector. A down link beam form device(107) multiplies the beam form weight by a user signal to perform a down link beam form function.
