Abstract:
1. A multi-antenna radio channel measurement system for measuring a radio channel, comprising: Control & Console Software to select a radio measurement mode, generate a probing signal for measurement, receive input parameters to be measured, and deliver the parameters to a baseband unit (BBU); the BBU to set a transmission/reception frequency band and bandwidth and set a timing using the selected radio measurement mode and the received input parameters so as to perform transmitting the probing signal for measurement and receiving a reception channel signal; a timing unit to synchronize a time with another radio channel measurement system to generate a transmission/reception synchronization signal, and provide the transmission/reception synchronization signal to the BBU; a transceiver unit (TRXU) to up-convert the probing signal for measurement and down-convert the reception channel signal; and a radio frequency (RF) front-end unit (RFFU) to switch to a suitable antenna according to a timing control signal of the BBU, wherein the received input parameters include the transmission/reception frequency band and bandwidth, a length of the probing signal for measurement, a number of transmission antennas, a number of reception antennas, and a parameter for setting a timing.
