Abstract:
Provided is a method for operating a terminal in a wireless communication system supporting device to device direct communication. The method comprises the steps of receiving respective reference signals from at least one transmitting terminal; estimating reference signals and a frequency offset between the respective reference signals, corresponding to the respective reference signals; and compensating for the transmission frequency of a voltage regulator oscillator of the terminal by using the results of frequency offset estimation.
Abstract:
The present invention relates to device-to-device (D2D) communication performing direct communication between nodes in a wireless communication system. The method of operating a terminal comprises the steps of generating sequences belonging to an orthogonal sequence set according to a sequence pattern corresponding to the priority of a link; and transmitting the sequences, one sequence per sub-block, through the sub-block within a channel as a signal for measuring the received power of other terminals.
Abstract:
The present invention relates to a method and an apparatus for generating and recovering a multiple-access signal in a mobile communication system. In order to generate the multiple-access signal according to the present invention, each transmitter transmits information by using all or a portion of given channel resources. At this time, a signal from each transmitter is mapped to an OFDM time-frequency resource space by a trellis modulation path. The mobile communication system according to the present invention allows the trellis modulation path of the plural transmitters to be mapped to the same resource space. According to the present invention, a receiver uses a symbol-by-symbol message passing method and a path linking method in order to effectively detect and discriminate the signals transmitted from the plural transmitters via the same channel resource space. The receiver, for more efficiently recovering the detected signals, uses a state space extending method, a reverse pre-decoding method and a successive interference cancelation method.

본 발명은 새로운 항생제에 관한 것으로, 보다 상세하게는 플루페나믹산을 유효성분으로 포함하는 항생 조성물에 관한 것으로, 상기 조성물이 단독으로 또는 다른 종래의 항생제와 함께 투여될 경우 소량으로도 좋은 치료효과를 나타내기에 항생제 과다 사용으로 인한 항생제 내성 문제 및 약제 독성, 부작용을 감소시킬 수 있다.
Abstract:
PURPOSE: A protein shelled platinum nanoparticle complex and a manufacturing method thereof are provided to synthesize uniform nanoparticle by controlling the reaction time and the ratio of protein shell and platinum. CONSTITUTION: A protein shell is composed of hollow protein. The diameter of internal space of the protein shell is between 1.5 and 6nm. The protein of the protein shell is composed of six or more sub units. Pores are arranged between the sub units in order to connect the inner side and the outer side of the protein. The diameter of the pore is between 1 and 4nm. A protein shelled platinum nanoparticle complex is surrounded by the protein shell.
