Wireless base station, wireless frames synchronization detection method used therein, and recording medium on which program therefor is recorded

摘要

In a baseband processing unit ( 1, 2 ) in a node-B, a path search circuit ( 11, 22 ) includes a path capture means ( 12, 22 ), path track transfer means ( 13, 23 ), and channel estimation means, all of which are primarily provided for the path capture, channel estimation, and RAKE combination. In the baseband processing unit ( 1, 2 ), a synchronization determination circuit ( 15, 25 ) includes a decoding means ( 16, 26 ) provided for decoding RAKE-combined data and calculating an average SIR per wireless frame and a correction calculation means ( 17, 27 ) 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.
