20100242550DRUM-TYPE WASHING MACHINE AND BEARING HOUSING STRUCTURE THEREOF - A drum type washing machine including a tub installed in a cabinet is disclosed. The drum type washing machine includes a drum performing washing, a motor rotating the drum, bearing housings having bearings to support a rotation shaft, a suspension connected to the bearing housings and the cabinet to mitigate vibration generated during rotation of the drum, a bracket installed to the bearing housings to form the rear side of the tub, and a gasket installed between the bracket and the tub to seal the tub and to prevent vibration from being transmitted from the bracket to the tub. Volumes of the tub and the drum can be easily increased without increasing the volume of the cabinet. Even when the volume of the washing machine is changed, only one of the tub and the bearing housings, which is not applicable to the drum type washing machine having the changed washing capacity, is selectively replaced. Thus parts can commonly used in various drum type washing machine having different volume.09-30-2010

20100177541VOLTAGE-SOURCED HVDC SYSTEM WITH MODULATION FUNCTION - A voltage-sourced High-Voltage Direct Current (HVDC) apparatus, which converts 3-phase AC voltage from a 3-phase AC power source into high voltage DC through a rectifier including switching elements, is provided. In the apparatus, a rectifier controller receives detected 3-phase currents, apparent power, and active power and generates D and Q-axis signals. A D/Q controller receives the signals and generates active power D-axis signal and apparent power Q-axis signal. A PWM unit generates PWM on/off signals for turning on/off the switching elements based on output signals from the D/Q controller. The D/Q controller includes a rotary converter to convert the D and Q-axis signals into AC signals and D and Q-axis order units coupled thereto, and generates the D and Q-axis signals through the order units. The PWM unit converts the D and Q-axis signals into 3-phase AC signals and compares them with 3-phase triangular waves to generate on/off signals for turning on/off the switching elements.07-15-2010

20090316809Method for transmitting channel quality information - There is provided a method for transmitting channel quality information in a wireless communication system. Over-all band of the wireless communication system is divided by a plurality of sub-bands. The method includes selecting a first sub-band having the highest CQI among the plurality of sub-bands, transmitting CQI of the first sub-band and transmitting CQI of a second sub-band, the second sub-band having the CQI lower than the first sub-band, wherein the number of CQI levels of the second sub-band is less than that of CQI levels of the first sub-band. Overheads incurred by CQI feedback can be reduced.12-24-2009
20100115380METHOD OF GENERATING CODEWORD IN WIRELESS COMMUNICATION SYSTEM - A method of generating a codeword for a control signal in a wireless communication system is provided. The method includes preparing a control signal and generating a codeword by applying a Reed-Muller (RM) extension matrix to the control signal. The RM extension matrix is generated by extending a RM basic matrix. A control signal can reliably be transmitted by the codeword with low complexity.05-06-2010

20100074309PHASE SHIFT BASED PRECODING METHOD AND TRANSCEIVER FOR SUPPORTING THE SAME - A method of transmitting data using a generalized phase shift based precoding or an extended phase shift precoding scheme in a multiple-antenna system using a plurality of subcarrier and a transceiver for supporting the same are disclosed. A phase shift based precoding matrix may be generalized and determined by a product of a diagonal matrix for phase shift and a unitary matrix for maintaining orthogonality in spatial domain. The diagonal matrix may be extended by a product of a precoding matrix for increasing channel power and the diagonal matrix for phase shift. The design of the transceiver can be simplified or communication efficiency can be improved by generalizing and extending the phase shift based precoding.03-25-2010
