Spread spectrum rake receiver |
摘要 |
The present invention is provided with a path timing detection unit for detecting path timings of a multi-path; a de-spreading timing for setting unit setting the detected path timings as de-spreading timings, and also for setting as de-spreading timings two timings that are symmetric to the other path timing by setting a delay time between timings of two paths in accordance with respective combinations of two paths of the multi-path on a time axis, while setting a path timing of one path of the two paths as a center; a plurality of correlators for obtaining respective de-spread signals of the reception signals corresponding to the respective set timings; and a signal synthesis unit for synthesizing outputs of the plurality of correlators.
