Abstract
The present invention relates to a multi-antenna radio channel measurement system and method for a two-way radio channel measurement, including: 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; a baseband unit (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; 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.
