<P>PROBLEM TO BE SOLVED: To provide a path search circuit capable of searching the closest path of a high power value at a high speed and improving communication quality even in the case that reception signals from a mobile station are made to fluctuate by external factors such as an obstacle and phading. <P>SOLUTION: A power comparison part 81 compares the path positions and power values of valid paths notified from a path detection part and decides whether or not the path of the maximum power value is the closest path. A correlator allocation part 82 sets correlator allocation for a high-speed search from control signals and the path position of the maximum power value from the power comparison part 81 and notifies a delay amount setting part 83 of correlator allocation information. The delay amount setting part 83 reads a delay amount set in a present slot from a memory 84, calculates the path position to perform correlation calculation in the next slot, transmits the delay amount to a delay circuit part 3 and stores the delay amount of the next slot to the memory 84 again. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
