PROBLEM TO BE SOLVED: To select a correct path, using a delay profile suited to the Doppler frequency. SOLUTION: Delay profile generators 101, 102 generate delay profiles from signals received by antennas, respectively. A delay profile adder 104 adds the delay profiles to generate an antenna combined delay profile. A path selector 105 selects an arbitrary number of path phases from each delay profile inputted via a switch 103, if the Doppler frequency is lower than a specified value. However, if it is higher than the prescribed value, it selects an optional number of path phases for each antenna from the antenna combined delay profile. |
