<P>PROBLEM TO BE SOLVED: To provide a radio receiver capable of reducing the application quantity of a memory without deteriorating reception accuracy and capable of efficiently performing synchronous holding operation. <P>SOLUTION: The radio receiver is provided with a 1st means for performing path search processing by dividing receiving data into a sample unit range in which path search is performed in each sample and a chip unit range in which path search is performed in each chip and calculating at least one of a sample unit correlation value and a chip unit correlation value about each detected path and a 2nd means for comparing the correlation value of the path detected by the 1st means with a prescribed threshold, judging that a path having a correlation value being equal to or larger than the threshold as an effective path and outputting the effective path. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
