Abstract: |
A multipath aligning method and apparatus in RAKE receiver used during the demodulation of physical channel dedecated to WCDMA is disclosed. A configurable multipath aligning apparatus for WCDMA users is used to implement the time alignment of user's multiple pathes, providing a prerequisite for RAKE merging. Said aligning method is characterized by that after the data of multiple pathes is configurated by buffer, the data outputs of multiple pathes are shifted to ensure their alignment. |
