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 () includes synchronization detecting

portion () for detecting synchronization chip timing of channel to be measured, asynchronization chip timing information portion accumulating information of detectedsynchronization chip timing, a correlation detecting portion () deriving a correlation valuebetween spreading code of the channel to be measured and a received signal forperforming communication with a base station and measurement of communicationquality with taking the detected synchronization chip timing as a reception chip timing, atime series generating portion () for generating a time series data of received signalvector after correlation detection, and a communication quality calculating portion () forcalculating communication quality from generated time series data.
