    • A user-concerned information recommendation system and method considering user's watching or listening time and the maximum playing time of contents are disclosed. The user-concerned information provision system includes a plurality of user terminals to provide contents transmitted from an external server to a user, a user-concerned information inference server to infer an association relationship between the contents based on information of maximum playing time and actual playing time of the contents provided to the user terminals, and a content provision server to provide a content requested by an arbitrary one of the user terminals and other contents associated with the requested content according to the inferred association relationship to the arbitrary one of the user terminals when receiving a request of the content from the arbitrary one of the user terminals, thereby providing more accurate user-concerned information to the user.

    • Disclosed is a method of signal detection. A received input signal is divided into a frame unit and each input signal present in a first frame and a second frame is transformed into a frequency signal. Then, first power spectrum information and second power spectrum information are computed utilizing the transformed frequency signal and a delta spectrum entropy value corresponding to a difference of the two computed power spectrum information is obtained. A predetermined input signal is included in a predetermined frame among the input signal after judging through comparing the delta spectrum entropy value with a critical value. Desired signal can be detected in a noisy environment including a noise signal by using the delta spectrum entropy value.
    • 公开了一种信号检测方法。 接收的输入信号被分成帧单位,并且存在于第一帧中的每个输入信号,并且将第二帧变换为频率信号。 然后,利用变换的频率信号计算第一功率谱信息和第二功率谱信息,并且获得与两个计算的功率谱信息的差对应的δ谱熵值。 在通过将Δ谱熵值与临界值进行比较判断之后,预定输入信号被包括在输入信号中的预定帧中。 可以通过使用δ谱熵值在包括噪声信号的噪声环境中检测期望的信号。
