<p><P>PROBLEM TO BE SOLVED: To improve estimation accuracy of a channel response estimation result. <P>SOLUTION: A channel response estimator 100 includes: a channel response estimation section 101 configured to estimate a channel response by correlation processing between a received signal and a known pattern signal; a path power calculation section 103 configured to measure power of each path within an outputted of the channel response estimation section; a noise floor calculation section 102 configured to measure noise power from the output of the channel response estimation section; a path determination section 104 configured to determine paths to be preserved by using the path power outputted from the path power calculation section and the noise power output from the noise floor calculation section; and a noise removal section 105 configured to remove values in time domain excepting the paths determined at the path determination section, from the output of the channel response estimation section. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
