Method, apparatus and receiving apparatus for multi-path searching

The invention is suitable for the moving communicating domain, it provides the multipath searching method, apparatus and the receiver, the said method includes: A. one sampling point is distilled from the a times super sampling base band signal by turns, the single time speed sampling point date stream is outputted: B. the single speed sampling point data stream and the local fake random code are conducted with the unbinding enlarging operation, the correlating apex energy of local fake random code moving relative to the said single time speed sampling point data stream phase; C. the position information of the several paths and the energy information are outputted according to the said peak energy; a is the natural number, a>1. By input data apparatus the point when the invention below sampling, the position information and the energy information of the several paths in the super sampling time precision are outputted, the higher searching precision can be realized, at the same time, the nicety of the searching can be improved highly.
