    • The present invention relates to a process for preparing polyethylene naphthalate, comprising the steps of: esterifying 2,6-naphthalene dicarboxylic acid and ethylene glycol, or glycols using the two materials as major material to obtain prepolymer which comprises bis(beta-hydroxyethyl)naphthalate or low polymer as main material; and performing polycondensation reaction to thereby prepare polyethylene naphthalate. The process of the present invention has advantages of: enabling esterification with a low molar ratio of ethylene glycol to reduce reaction time, thereby increasing process efficiency; minimizing formation of side reaction products to improve properties; and preventing deterioration of the products by performing polycondensation at a low temperature to thereby obtain polyethylene naphthalate polymers of high quality.

    • A system and method for sound source separation. The system and method use a beamforming technique. The sound source separation system includes a windowing processor; a DFT transformer; a transfer function estimator; and a noise estimator. The system also includes a voice signal extractor that cancels individual voice signals, except an individual voice signal that is desired to be extracted among individual voice signals, from the integrated voice signals. The system further includes a voice signal detector that cancels a noise part provided through the noise estimator from a transfer function of an individual voice signal which is desired to be detected and extracts a noise-canceled individual voice signal. Even when two or more sound sources are simultaneously input, the sound sources can be separated from each other and separately stored and managed, or an initial sound source can be stored and managed.

    • An adaptive mode control apparatus and method for adaptive beamforming based on detection of a user direction sound are provided. The adaptive mode control apparatus includes a signal intensity detector that searches for signal intensity of each designated direction to detect signal intensity having a maximum value when a voice signal of each direction is input through at least one microphone; and an adaptive mode controller that compares the signal intensity having the maximum value detected through the signal intensity detector with a threshold value and determines whether to perform an adaptive mode of a Generalized Sidelobe Canceller (GSC) according to the comparison results. Therefore, a lack of control of adaptation of an adaptive filter of the conventional art is solved. That is, as one condition for guaranteeing performance of adaptive beamforming, adaptation of an adaptive filter is not performed when noise of a sound with a high autocorrelation is cancelled.
    • 提供了一种基于用户方向声音检测的自适应波束成形的自适应模式控制装置和方法。 自适应模式控制装置包括信号强度检测器,当通过至少一个麦克风输入每个方向的语音信号时,搜索每个指定方向的信号强度以检测具有最大值的信号强度; 以及自适应模式控制器,其将具有通过信号强度检测器检测到的最大值的信号强度与阈值进行比较,并且根据比较结果确定是否执行广义旁瓣消除器(GSC)的自适应模式。 因此,解决了传统技术的自适应滤波器的适应性缺乏控制。 也就是说,作为用于保证自适应波束形成的性能的一个条件,当取消具有高自相关性的声音的噪声时,不执行自适应滤波器的自适应。
