摘要： This invention relates to a calibration method of modulation power for DVB-H test apparatus for reducing the calibration time for the power loss in the RF cable to half through calibration using the expected power loss of the modulated wave at an arbitrary frequency based on the measured power losses of the continuous wave over frequencies in the RF cable. The calibration method of modulation power for DVB-H test apparatus that is performed by the computer with installed calibration program therein and connected to the power meter of the DVB-H test apparatus, comprises and includes the steps of: commanding DVB-H test apparatus to output continuous waves having frequencies from the start frequency to the stop frequency with increment of frequency step in accordance with the preset power level; storing CW power offset, that is the difference between the actual power level and the preset power level, to the table after receiving actual power level of continuous waves having frequencies from the start frequency to the stop frequency with increment of frequency step from the power meter; commanding DVB-H test apparatus to output a modulated wave that carries data on a continuous wave having an arbitrary frequency between the start frequency and the stop frequency, thereafter receiving actual output power level from the power meter, and calculating the modulation power offset between the continuous wave and the modulated wave at the corresponding arbitrary frequency, thereafter commanding DVB-H test apparatus to output the preset power level added with the power offset of the continuous wave and the power offset of the modulated wave when transmitting the modulated wave.

摘要： Disclosed herein is a digital re-sampling apparatus. The digital re-sampling apparatus includes a sample buffer, a sample buffer control unit, a filter bank, a first delay bank, a fractional delay constant table, a combiner bank, and a second delay bank. The sample buffer temporarily stores an input sample in synchronization with an input sampling frequency. The sample buffer control unit controls writing and reading operations. The filter bank includes a number of digital filters equal to the number of stages, and filters the input sample. The first delay bank differentially delays a filter output value. The fractional delay constant table stores information about re-sampling time. The combiner bank includes a number of adders and multipliers, performs an operation, and outputs a re-sampled value. The second delay bank causes a delay so that output of each combiner can be synchronized with each output of the fractional delay constant table.

摘要： An apparatus for generating indexes of an interleaver for input data comprises: a main processor for calculating an index for a predetermined bit of the input data; and an index operator for receiving the index calculated by the main processor, calculating in parallel indexes for bits after the predetermined bit, and deriving a plurality of indexes. The main processor calculates the index for ith to (i+15)th bits of the input data where i is an integer equal to or larger than 0, and transfers a result of (128*f2)modK to the index operator. The index operator calculates an index for an (i+j+16)th bit where j is an integer which satisfies 0≦j≦7 by using an equation of Π(i+j+16)=(2*Π(i+j+8)−Π(i+j)+128*f2)modK where K is a size of the input data and f2 is a coefficient calculated from K.

摘要： Disclosed herein are an apparatus and method for measuring quality of an image received via a communication network. The apparatus includes an interface unit, a codec unit, a test image detection unit, and a Mean Opinion Score (MOS) measurement unit. The interface unit receives an image, including a start synchronization image and a test image via a communication network. The codec unit decodes the received image into a color signal. The test image detection unit detects any one value of brightness, saturation and hue information of the color signal input from the codec unit, calculates an average value for each frame, and detects the test image from the received image based on the calculated average value. The MOS measurement unit synchronizes the test image with a corresponding reference image, compares the quality of the test image with the quality of the reference image, calculates an MOS value based on the results of the comparison, and outputs the MOS value.

摘要： Disclosed herein is a time synchronizing apparatus for a mobile WiMAX analyzer. The time synchronizing apparatus includes a Global Positioning System (GPS) receiver and a synchronization control unit. The GPS receiver outputs a GPS signal that is synchronized with the GPS time using information received from a GPS satellite. The synchronization control unit compares the GPS signal and a reference signal, which is generated using an internal clock, and controls synchronization according to the result of the comparison. The synchronization control unit includes an oscillator, a divider, an offset comparison unit and a processor. The oscillator outputs an oscillation signal having a predetermined frequency. The divider divides the oscillation signal into the reference signal. The offset comparison unit compares the differences between the GPS signal and the reference signal, and outputs the result value of the comparison. The processor controls the oscillation frequency of the oscillator until the result value satisfies a predetermined reference value.
