Receiving apparatus, receiving method and program thereof
摘要:
A receiving apparatus adjusts a path search window width in path search processing according to the saved timing information, after saving timing information detected at the time of cell search processing. A Radio Frequency (RF) unit receives signals which are sent from a base station and transmitted via a plurality of paths (multi-path). A cell search unit detects scrambling codes specific to the base station in received signals and generates timing information corresponding to the multi-path signals when the same scrambling code is detected in a plurality of timings. A path timing memory unit saves each of the timing information for each of the multi-path signals. A path search unit controls a search window width and search start timing in reference to the timing information of the same scrambling code to perform a path search.
