Title:
RECEIVER DEVICE, RECEIVING METHOD, CONTROL PROGRAM AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2012/169303
Kind Code:
A1
Abstract:
The objective of the present invention is to allow high-precision determination of a synchronization position. The present invention is a receiver device for determining a prior path position on the basis of a received multipath, which is provided with: a propagation path suitability calculation unit (509) which estimates a channel impulse response using a frequency response estimate in order to calculate, for each path, a propagation path suitability indicating the suitability between the estimate and the path; an unnecessary candidate path removal unit (511) for removing candidate paths which do not increase the propagation path suitability; a path extraction unit (515) for extracting at least one candidate path which increases the propagation path suitability in order to treat the same as an extracted path; and a synchronization correction assessment unit (513) which determines the temporal position of the candidate path for which the delay time is smallest among the extracted paths as the prior path position.
