摘要：A mobile communication system (1) according to the present inventioncomprises base station (30) and mobile station (10). The base station (30) sends a pilot

symbol sequence known to the mobile station (10), to the mobile station (10), using aplurality of carriers for downward channels, and performs communication with the mobilestation (10) while multiplying the channels by scrambling codes. The mobile station (10) isprovided with a peak detector (17) for calculating cross correlation allowing for a phasedifference of the scrambling codes between pilot symbol sequences received from thebase station (30), thereby detecting a radio frame boundary.
