Apparatus and method for analyzing identification signal based on partial correlation
First Claim
1. An apparatus for analyzing identification (ID) signals, comprising:
- a receiver for receiving a signal with an ID signal added thereto from a transmitting part, wherein the ID signal added has a length N;
a signal converter for converting the received signal into a signal of a desired band;
an ID signal generator for generating ID signals that are identical to the ID signals added by the transmitting part to the received signal,wherein the generated ID signals that are identical to the ID signals have a length of M, and wherein M is less than N;
a partial correlator for calculating partial correlation values between the converted signals acquired in the signal converter and the created ID signals acquired in the ID signal generator based on partial correlation; and
extracting a channel profile for the received signal, andwherein the extracted channel profile is configured from the partial correlation values acquired in the partial correlator.

Abstract
Provided is an apparatus and method for analyzing identification (ID) signals by converting radio frequency (RF) signals which are transmitted with an ID signal added thereto by a transmitting part, e.g., a plurality of transmitters or repeaters, into signals of a desired band; creating ID signals that are identical to the ID signals added to the RF signals; calculating correlation values between the converted signals and the created ID signals based on partial correlation; and extracting channel profile of multi-path signals caused by a channel between the transmitting part and the ID signal analyzing apparatus from the correlation value. The technology of the present research is applied to broadcasting and communication.
