摘要:
The present invention relates to an automatic calibration method of a test device for testing a wireless communication system such as a DVB-H or the like, a device, and a manufacturing method thereof, and more specifically, to a calibration method and device for providing an automatic calibration data generation function, in which the same frequency characteristic of the test device is maintained in various frequency bands and the test device is capable of generating an exact and reliable test signal. The calibration method of the present invention comprises the steps of: (a) extracting the size of a removal target signal component on the basis of a calibration signal generated from the test device; (b) extracting a change value of the size of the removal target signal component; (c) adjusting at least one calibration parameter on the basis of the change value, and transmitting an adjusted calibration parameter value to the test device, and calculating a calibration parameter value which minimizes the size of the removal target signal component, and generating the calculated value as calibration data, by repeatedly performing the steps (a) to (c).

The present invention relates to a method of automatically controlling the volume level of communication speech for Mean Opinion Score (MOS) measurement, which, before evaluating the quality of communication speech using a MOS measurement method, automatically controls the volume level of actual communication speech to a predetermined optimal level, thus improving the reliability of MOS values.The present invention provides a method of automatically controlling a volume level of communication speech for MOS measurement using MOS measurement equipment, the MOS measurement equipment calculating an MOS value based on results obtained by comparing a speech signal, which is received via a voice communication network, with a reference speech signal, the method comprising the steps of (a) when an audio signal, including a speech signal, is received from counterpart MOS measurement equipment in a predetermined format, measuring the volume level of the speech signal and comparing the volume level of the measured speech signal with a reference volume level; (b) transmitting a predetermined intrinsic audible frequency signal, which corresponds to ‘proper,’ ‘excess’ or ‘insufficiency’ information resulting from the comparison, to the counterpart MOS measurement equipment; and (c) the counterpart MOS measurement equipment interpreting the predetermined intrinsic audible frequency signal, which corresponds to the ‘proper,’ ‘excess’ or ‘insufficiency’ information, and controlling the volume level of the communication speech.

Disclosed herein is a method of analyzing portable Internet signals in a measuring instrument. The method includes the steps of (a) acquiring synchronization using a preamble included in a currently received frame, (b) acquiring the access parameters of a DL_MAP included in the frame, and checking the validity of the DL_MAP, (c) if, as a result of the check at step (b), the DL_MAP is determined to be valid, acquiring downlink parameters and burst configuration information by interpreting the DL_MAP, and (e) performing a variety of diagnoses, including evaluation of signal quality for each burst, using the parameters and the burst configuration information.
