PROBLEM TO BE SOLVED: To provide a multi-pilot tone detection method and a matching filter by which a filter circuit scale can be reduced in the case that a preamble signal consists of a multi-pilot tone signal. SOLUTION: The matching filter detecting multi-pilot tone signals (f1+f2+...+fn) and in matching with the multi-pilot tone signals (f1+f2+...+fn) of a detection object is configured with filters that are matched with each pilot tone signal of the multi-pilot tone signals (f1+f2+...+fn). |
