<p>A radio receiver (1102) receives a reception signal whose band is limited by using a filter. A delay profile creator (1104) creates a continuous delay profile for each mid-amble shift. A distortion component creator (1106) multiplies the power value of the head sample of each mid-amble shift by a filter coefficient, thereby creating a head path distortion component. A removal unit (1107) removes the head path distortion component of the adjacent backward mid-amble shift from a predetermined backward sample in the delay profile of each mid-amble shift. A path selector (1108) selects as a path a sample whose power value is equal to or above a threshold value from the delay profile after the head path distortion component is removed.</p> |
