    摘要： A method for evaluating video quality based on a non-reference video to evaluate the quality of a received video using artificial intelligence composed of convolutional neural networks (CNN) and recurrent neural networks (RNN) capable of setting a learning range, includes: (a) extracting RGB values for one frame of a video; (b) obtaining an output by providing the extracted RGB values to CNN No. 1; (c) obtaining an output by providing the extracted RGB values n times to a CNN; (d) repeating (a) to (c) for all frames and merging outputs of all CNNs; (e) obtaining the output of the RNN with the time dimension reduced to 1 after passing the merged output value to the RNN; and (f) after applying a regression algorithm to the final output of the RNN, predicting this value as video quality value.

    摘要： Provided is a method of calibrating a power for a multiple input and multiple output-orthogonal frequency division multiplexing transmitter having a plurality of antennas via a measurement equipment, the method including: receiving a cyclic delay diversity (CDD) signal simultaneously output from the transmitter to obtain a starting point of a frame of a corresponding signal; performing a fast Fourier transform on a sample proceeded from the starting point by an extent of a maximum CDD delay; calculating a channel coefficient; calculating a channel impulse response and a power of the channel impulse response; converting CDD delay values of each antenna into values in units of samples by using a sampling rate in the channel impulse response; mapping a peak point position of the channel impulse response to each antenna using CDD delay sample values; and simultaneously performing a power calibration of each antenna based on each peak point power.

    摘要： Provided is a system for testing mobile handover which makes it possible to test a handover operation on a mobile side by providing an actual base station with a radio wave environment for causing mobile devices to move. The system is intended to test whether or not a handover operation of a mobile present in the service areas of at least three base stations is performed without interrupting service while the mobile moves from the service area of a currently connected base station to another spot.

    摘要： A method of measuring a call delay time by synchronizing times of a replaying part and a recording part in a call delay time measuring device using an interrupting hardware method. The method includes reading an original WAV file when a replaying CPU receives a command, waiting for writing to a DAC buffer of a replaying CODEC, transferring a signal of recording-ready to a recording CPU, generating a recording WAV file by the recording CPU, waiting for reading from an ADC buffer of a recording CODEC, transferring a signal of complete recording-ready to the replaying CPU, recording the original WAV file, replaying the original WAV file and simultaneously transferring a signal of recording-start to the recording CPU, and reading audio data from the ADC buffer of the recording part by the recording CPU and recording the audio data to the recording WAV file.

    摘要： Disclosed herein is a method of detecting a physical downlink control channel (PDCCH) in a long-term evolution (LTE) system. In this method, one is selected from among possible PDCCH formats for received base station signals, and a signal corresponding to the length of the selected PDCCH format is retrieved. Thereafter, one is selected from among one or more of possible DCI formats that have not been selected yet. Thereafter, decoding is performed using the retrieved signal and the selected DCI format. Finally, a remainder is obtained by dividing the decoded signal by a cyclic redundancy check (CRC) pattern, and the remainder is stored as RNTI information, along with the selected DCI and the DCI format.
