초록
The present invention relates to a multi-antenna radio channel measurement system and method which generates a Time Division Duplex (TDD) timing signal and measures a two-way radio channel. The multi-antenna radio channel measurement system which measures a probing signal for measuring a radio channel, the multi-antenna radio channel measurement system including: a baseband unit alternately transmits the probing signal for measurement and receives the received channel signal to be measured based on a TDD synchronization time; a synchronization unit which obtains time synchronization with the other radio channel measurement system, generates a transmission/reception synchronization signal, and provides the transmission/reception synchronization signal to the baseband unit; a transceiver unit which up converts the probing signal for measurement and down converts the received channel signal; and a radio frequency (RF) front-end unit which switches suitable antennas according to a timing control signal of the baseband unit.
