Abstract
In a baseband processing unit in a node-B, a path search circuit includes a path capture unit, path track transfer unit, and channel estimation unit, all of which are primarily provided for the path capture, channel estimation, and RAKE combination. In the baseband processing unit, a synchronization determination circuit includes a decoding unit provided for decoding RAKE-combined data and calculating an average SIR per wireless frame and a correction calculation unit primarily provided for reliably and stably detecting wireless frame synchronization. The processing time required to detect synchronization establishment during wireless frame synchronization determination is shortened.
