  • Publication number: 20240094077
    Abstract: An electrode connection cause determination system includes a position measuring instrument. The position measuring instrument is configured to, when an electrode moves between an unwinder and a rewinder in a roll-to-roll state, acquire coordinate value data based on a longitudinal position of the electrode determined according to a rotation amount of the rewinder. The system includes a signal generator configured to generate a connection advance notice signal if the electrode includes a connecting portion corresponding to a cause event, a seam detector configured to detect a seam attached onto the electrode after the connection advance notice signal is generated, and a determination unit configured to, when the seam is detected within a predetermined distance from a first coordinate value of the electrode after the connection advance notice signal is generated, determine that a connection cause of an electrode connection by the seam corresponds to the cause event.

  • Patent number: 8375769
    Abstract: An apparatus and method for measuring a Signal-to-Interference-plus-Noise Ratio (SINR) by controlling a residual gain in a high speed packet access system are provided. The apparatus includes a gain controller for measuring an intensity of a signal outputted from a residual gain controller, for outputting a gain control signal for controlling a gain of an interval of a preset gain resolution of a radio frequency integrated circuit according to the intensity of measured signal, and for outputting a residual gain value for controlling a residual gain less than the preset gain resolution, wherein the radio frequency integrated circuit gain-controls a signal inputted according to the gain control signal, and the residual gain controller multiplies the gain-controlled signal by the residual gain value to compensate the residual gain.

  • Patent number: 8345806
    Abstract: An apparatus and a method are provided for detecting N number of TX signals in a MIMO wireless communication system. The apparatus includes an RF processor, a channel estimator, and a signal detector. The RF processor converts signals, received through multiple antennas, into baseband signals. The channel estimator estimates channel information of the respective antennas by using the received signals. The signal detector arranges the baseband signals of the respective antennas on the basis of the channel information, calculates a threshold value of each stage, and selects symbols with a cumulative metric smaller than or equal to the threshold value as candidates at each stage, to detect a TX signal vector with N number of symbols.

  • Patent number: 8005170
    Abstract: A method and apparatus for detecting a signal in a communication system using at least two transmit antennas are provided. The signal detection method and apparatus includes selecting a symbol corresponding to a lowest branch metric from among symbols, the number of which corresponds to a modulation scheme, determining a candidate symbol by extending a process of selecting a symbol corresponding to a lowest branch metric from among the selected symbols, to a number which is less by one than the number of the transmit antennas, setting an accumulated branch metric of the candidate symbol as a threshold, removing a symbol having an accumulated branch metric higher than the threshold, and selecting, as a last received symbol, a symbol corresponding to a path having the lowest accumulated branch metric among paths selected without being removed until a last stage.
