Title:
DELAYED PROFILE GENERATING DEVICE
Document Type and Number:
Japanese Patent JP2004289534
Kind Code:
A
Abstract:

To flexibly adapt to a variety of styles of a multipath and wide variation and to precisely and stably obtain a delay profile with resolution lower than chip cycles.

A delay profile generating device is equipped with a phase shifting means 11 of generating a plurality of out-of-phase signals by sequentially shifting the phase of a single signal generated as the product with a single code series whose autocorrelation on the time base is steep and a phase analyzing means 12 of obtaining a distribution of components included in the single signal by phases as levels of products by all combinations of one of two time functions differing in phases over values corresponding to a quarter of cycles of bits or words constituting the single code series, the single code series, and one of a plurality of signals.
