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.
