    Abstract: A field emission display apparatus including a field emission display panel and a driving device for the field emission display panel. The driving device includes a power supply unit, the power supply unit including an abnormal current detection unit and a discharge circuit. The abnormal current detection unit generates an arc-current detection signal when the value of a current flowing between a negative anode voltage terminal of the field emission display panel and a common ground line is larger than an upper limit. The discharge circuit generates a short circuit between an anode plate of the field emission display panel and the negative anode voltage terminal when the arc-current detection signal is generated from the abnormal current detection unit.

    Abstract: An apparatus and method for receiving data in a mobile station for a mobile communication system using multi-user packet data are provided, in which a preamble power measurer measures preamble power of the multi-user packet data received from a base station and transmits the result value to a controller. The controller compares the measured power with a predetermined threshold, simultaneously decodes the multi-user packet data according to all transport formats if the measured power is lower than the threshold, and decodes the multi-user packet data according to a predetermined transport format if the measured power is higher than or equal to the threshold. A plurality of decoders decode the received multi-user packet data according to a control signal from the controller, wherein the number of the decoders depends upon the total number of transport formats for the multi-user packet data.

    Abstract: An apparatus and a method for detecting traffic channel signal transmission in a rake receiver may advantageously ensure stable and accurate detection performance in performing continuous/discontinuous transmission detection of traffic channels with a rake receiver in a mobile communication system based upon CDMA 2000 standards by making sufficiently spaced distribution in traffic channel signal-to-noise ratios estimated in continuous/discontinuous transmission. The method includes compensating traffic channel signals according to fingers, respectively, by using estimated pilot channel signals; combining the compensated finger-based traffic channel signals and estimating signal-to-noise ratios for traffic channels; and comparing the estimated signal-to-noise ratios with a preset threshold value, respectively, to detect continuous or discontinuous transmission of the traffic channels based upon comparison results.

    Abstract: A linear compensation system of a digital TV relay or other apparatus preferably includes a transmitting unit configured to modulate a data to an intermediate frequency (IF) signal, up convert the IF signal to an RF signal, and amplify the RF signal to a predetermined level using a high power amplifier (HPA). The system also includes a linear compensation unit to preferably directly vary a step size of an adaptive equalizer according to whether a signal-to-noise ratio (SNR) or an error vector magnitude (EVM) for an output signal of the HPA satisfies an advanced television systems committee (ATSC) or other standard. The linear compensation unit is thus configured to output an improved linear compensation coefficient to a modulator of the transmitting unit.
