<P>PROBLEM TO BE SOLVED: To provide a synchronous capture method, capable of obtaining synchronous capturing for measurements with high speed, high accuracy, and high reliability, using a common pilot channel, in transmission diversity operation, being transmitted from a base station at all the time, and to provide a device thereof. <P>SOLUTION: When measuring communication quality at a mobile receiving station while using a common pilot channel, in transmission diversity, being transmitted at all the time from a base station of a mobile communication system employing a CDMA cellular scheme, at the mobile receiving station, a received signal vector, obtained by performing correlation detection on a received signal by the unit of a symbol, is separated into received signal vectors for each of transmission antennas of the base station by addition/subtraction before and after the symbol and on the basis of a value power-adding the received signal vectors, synchronization chip timing is determined. <P>COPYRIGHT: (C)2009,JPO&INPIT |
