Patent ID: 8358601

Claim:
A multi-antenna radio channel measurement system which measures a probing signal for measuring a radio channel, the multi-antenna radio channel measurement system comprising: a baseband unit which synchronizes with another radio channel measurement system based on a Time Division Duplex (TDD) synchronization time, and alternately transmits the probing signal for measurement and receives a received channel signal to be measured; 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, and wherein the baseband unit comprises: a timing control block which generates a transmission timing control signal suitable for transmission timing in a TDD mode based on a predetermined synchronization parameter and the transmission/reception synchronization signal of the synchronization unit; a transmission memory which stores the signal for measurement; a transmission digital baseband block which downloads the probing signal for measurement, stores the probing signal for measurement in the transmission memory, and outputs the probing signal for measurement according to the transmission timing control signal; and a micro-processor which controls the predetermined synchronization parameter to be received from a control and console software and to be provided to the timing control block, controls the probing signal for measurement to be received from the control and console software and to be transmitted to the transmission digital baseband block, and controls the probing signal for measurement to be transmitted through the transmission digital baseband block according to the transmission timing control signal generated in the timing control block.
