Patent ID: 7151792

Claim:
A rake receiver used in a spectrum spreading communication system, comprising: a path timing detection unit detecting path timings of a multi-path from reception signals; a de-spreading timing setting unit setting the detected path timings as de-spreading timings, wherein said de-spreading timing setting unit sets two timings in relation to a timing of a first path of a two-path pair on a time axis by setting a delay time between timings of the two-path pair while setting the timing of a second path of said two-path pair as a center such that one of said two set timings is in a symmetry across said center with said timing of the first path, for every combination of two-path pairs among said multi-path; a plurality of correlators respectively obtaining de-spread signals of the reception signals corresponding to the respective set timings; and a signal synthesis unit synthesizing outputs of the plurality of correlators.
