ABSTRACT:
A finger allocating section5allocates path timings corresponding to peak positions of a plurality of radio waves to separate finger sections6and further decides a path tracking range in each of the finger sections6on the basis of respective distances of peak positions in the plurality of radio waves. For instance, when distances between peak positions in a plurality of radio waves received from a base station30are narrow, the finger allocating section narrows a variable path tracking range in each of the finger sections6. Digital base band signals are inversely spread within a path tracking range decided by the finger allocating section5among segments positioned before and after a path timing allocated by the finger allocating section5. In this way, a system and method is provided for positively receiving a plurality of radio waves in a manner that prevents deterioration of reception.
