ABSTRACT:
A weight vector of a precedent frame calculated by a weight vector calculator (4) and stored in a memory (3) is applied to a signal received through a plurality of antennas (ANT1, . . . ANTn) for removing an interference wave component. A synchronous position is detected from the signal subjected to removal of the interference wave component by a method of correlation synchronization, and supplied to the weight vector calculator (4). The weight vector calculator (4) executes calculation of a weight vector with the detected synchronous position as a start position. Thus, when signals of the same frequency are received in a CS in an overlapping manner, the synchronous position of a signal received from a desired PS can be correctly specified.
