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

摘要

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 (tau₁-tau_{1 3}) in the delay profile are measured. Among the measured time spaces, a maximum time space (tau₈) 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.
