Leading wave position detecting unit, receiver, leading position detecting unit, leading wave position detecting method and leading position detecting method

Abstract

A leading wave position detecting unit and method etc. is provided for detecting the position of the leading wave in a delay profile. Time spaces between sampled values (τ 1 -τ 1 3 ) in the delay profile are measured. Among the measured time spaces, a maximum time space (τ 8 ) is determined, and the position of its immediately following sampled value (sampled value (h)) is detected as a leading position. The initial peak of the sampled values after the leading position detected (position of sampled value (j)) is determined as a leading wave position.

1 . A leading position detecting unit for detecting a leading position in a delay profile, said leading position detecting unit comprising: 
 time space measuring means for measuring time spaces between sampled values of a delay profile sampled along a delay time axis; and    leading position detecting means for detecting a leading position in consideration of time spaces measured by said time space measuring means as a leading position.
