摘要：In order to perform synchronization detection with high speed, high precisionand high reliability and to measure communication quality (propagation characteristics) athigh precision and high efficiency, a mobile station (202) includes synchronizationdetecting portion (221) for detecting synchronization chip timing of channel to bemeasured, a synchronization chip timing information portion accumulating information ofdetected synchronization chip timing, a correlation detecting portion (222) deriving acorrelation value between spreading code of the channel to be measured and a receivedsignal for performing communication with a base station and measurement ofcommunication quality with taking the detected synchronization chip timing as areception chip timing, a time series generating portion (223) for generating a time seriesdata of received signal vector after correlation detection, and a communication qualitycalculating portion (224) for calculating communication quality from generated timeseries data.
