<P>PROBLEM TO BE SOLVED: To improve reception quality of transmission data in a mobile station by preventing interference between a system for synchronization and the transmission data. <P>SOLUTION: In a base station device 100, a frame forming section 120 arranges transmission data and a system to be used for identifying a frame timing and a code group to which a base station scrambling code belongs in a receiver side so that they may not be overlapped in the same symbol to be specified by a sub-carrier and a time, and forms a frame, and an RF transmission section 150 transmits the frame. In a mobile station device 200, an RF receiving section 210 receives the frame from the base station device 100, an SCH correlation value calculating section 240 multiplies the frame by all the candidates of the system one by one to take correlation, and a frame timing/code group detecting section 250 detects the frame timing and the code group on the basis of the correlation value obtained from the SCH correlation value calculating section 240. <P>COPYRIGHT: (C)2007,JPO&INPIT |
