SIGNAL QUALITY MEASURING APPARATUS FOR WIBRO SYSTEM AND THE METHOD THEREOF
First Claim
1. A signal quality measuring apparatus for a WiBro system, comprising:
- a WiBro signal reception unit for receiving a WiBro signal from each base station;
a preamble code correlation unit for searching the WiBro signal for a number of preamble codes equal to a number of base stations for which measurement of signal quality measurement is required;
a channel compensation/demodulation unit for acquiring information of a Frame Control Header (FCH) section and a DownLink-MAP (DL-MAP) section with reference to the preamble codes found by the preamble code correlation unit, and demodulating information of a unique number of the base station; and
a control unit for collecting and processing the information about the unique number of the base station demodulated by the channel compensation/demodulation unit, and information about signal quality of the preamble codes found by the preamble code correlation unit.

Abstract
Disclosed herein are a signal quality measuring apparatus for the WiBro system and a method thereof. The signal quality measuring apparatus for a WiBro system includes a WiBro signal reception unit, a preamble code correlation unit, a channel compensation/demodulation unit, and a control unit. The WiBro signal reception unit receives a WiBro signal from each base station. The preamble code correlation unit searches the WiBro signal for a number of preamble codes equal to the number of base stations for which measurement of signal quality measurement is required. The channel compensation/demodulation unit acquires the information of a Frame Control Header (FCH) section and a DownLink-MAP (DL-MAP) section with reference to the preamble codes found by the preamble code correlation unit, and demodulates the information of a unique number of the base station. The control unit collects and processes the information about the unique number of the base station demodulated by the channel compensation/demodulation unit, and information about signal quality of the preamble codes found by the preamble code correlation unit.

3. A signal quality measurement method for a WiBro system, comprising the steps of:
-
(a) receiving a WiBro signal from each base station and acquiring a number of preamble codes equal to a number of respective base stations; (b) searching for a descending order of correlation value between the acquired preamble codes across all segments; (c) acquiring FCH information based on the segments of the acquired preamble codes; (d) acquiring information about a unique number of the base station included in data within a DL-MAP by accessing unique number information of the corresponding base station using the acquired FCH information; and (e) arranging and outputting information about acquired unique numbers of respective base stations and signal quality thereof in descending order of correlation value. - View Dependent Claims (4)
