<p>PURPOSE: A device for measuring a VSWR(Voltage Standing Wave Ratio) of a reception antenna in a mobile communication system is provided to use a single tone generator as adding an RSSI circuit without using a closed loop power control of a base station by using an MS(Mobile Station) building a BADA(Base-station Analyzer and Diagnostic monitor Assembly) therein, thereby measuring a VSWR one time. CONSTITUTION: A BADA(200) builds a single tone generator(202) for generating and outputting a single frequency signal, and controls forward and reverse paths. A transmitter/receiver antenna(221) simultaneously performs transmitting/receiving functions. A reception antenna(222) performs a receiving function only. Bidirectional couplers(223,224) are connected to the BADA(200) and a base station system, respectively, and extract signals inputted to the forward and reverse paths. An RSSI unit(231) calculates RSSIs of the paths, respectively. A BSP(Base Station Processor)(233) measures a VSWR of the reception antenna(222) by using differences between the forward RSSI and the reverse RSSI.</p> |
