Abstract:
1. A receiver apparatus comprising a propagation channel estimating unit that estimates a propagation channel, wherein the propagation channel estimating unit includes a path detector unit that repeatedly performs a process of detecting paths in the order of increase of a propagation channel goodness of fit, wherein the path detector unit estimates a plurality of channel impulse responses each of which uses selected paths and a candidate path, calculates the propagation channel goodness of fit of each of the channel impulse responses, removes the candidate paths of which the propagation channel goodness's of fit are smaller than a pre-calculated channel propagation goodness of fit of a channel impulse response that uses only the selected paths, moves at least one of the candidate paths in the descending order of the propagation channel goodness's of fit into the selected paths, and iterates a process of detecting paths that consists of the estimation of the channel impulse response, the calculation of the propagation channel goodness's of fit, and the selection of the candidate paths.
