Abstract:
This invention relates to a method of producing aromatics and light paraffins from hydrocarbonaceous oils derived from oil, coal or wood, including partially saturating and hydrocracking the oils derived from oil in a hydrogenation and reaction area, separating them depending on the number of carbons, recirculating heavy oils having 11 or more carbons to the hydrogenation and reaction area, feeding oils suitable for producing BTX to an aromatic separation process and a transalkylation process to recover aromatics, and feeding hydrocarbonaceous components having 5 or fewer carbons to a light separation process, thus obtaining light paraffins.

Abstract:
An audio data processing apparatus and method to reduce wind noise. The apparatus includes a wind noise detecting unit to detect a wind noise section from an input audio signal, and a signal processing unit to reduce a low-frequency band signal of the input audio signal in the detected wind noise section. The apparatus determines whether wind is present and automatically reduces wind noise based on the determined result. Accordingly, the apparatus can effectively reduce wind noise.

Abstract:
Disclosed is a MAC controller of a network printing device having a MAC controller for transmitting/receiving a packet over a network, and at least one bus master. The MAC controller includes a buffer for temporarily storing the packet, and an IP header analyzer for analyzing an IP header of the packet stored in the buffer, comparing an IP address of the packet with a pre-assigned IP address, and determining based on the comparison result, whether to receive the packet. The MAC controller can be advantageously used for maximizing the bus bandwidth for use in the network printing device having a single processor by minimizing unnecessary packets' accesses.

The data interfacing apparatus includes a data receiving unit to receive execution packet data to execute functions of the a network electronic device data and control packet data to control the network electronic device from a host via a network; a data storage controlling unit to control storage of the execution packet data and/or the control packet data; a data storage unit to store the execution packet data and/or the control packet data; a network processing unit to generate transfer descriptors of the execution packet data stored in the data storage unit and/or generate a control block of the control packet data stored in the data storage unit; and an interface controlling unit to transmit packet data corresponding to the transfer descriptors to the network electronic device through direct memory access and/or transmit packet data corresponding to the control block to the network electronic device, and to receive response packet data from the network electronic device as a response to the control packet data. Accordingly, data is transmitted between a network electronic device and the data interfacing apparatus at high speeds by reducing local bus bandwidth occupancy rates of the network electronic device and the data interfacing apparatus. In addition, it is possible to simplify codes and minimize header information by using a streaming channel through direct memory access to skip pretreatment operations to interpret command languages.

Abstract:
A method for converting source data to a channel-modulated signal having a plurality of pairs of in-phase (I) and quadrature-phase (Q) data in a mobile station, wherein the mobile station uses at least one channel, includes the steps of: a) encoding the source data to generate at least one data part and a control part; b) generating at least one spreading code to be allocated to the channel, wherein each spreading code is selected on the basis of a data rate of the data part and the control part and spreading codes are selected so that two consecutive pairs of the I and Q data are correspondent to two points located on same point or symmetrical with respect to a zero point on a phase domain; and c) spreading the control part and the data part by using the spreading code, to thereby generate the channel-modulated signal. The method is capable of improving a power efficiency of a mobile station by reducing a peak-to-average power ratio in a mobile communication system.
