Patent application numberDescriptionPublished
20100141477APPARATUS AND METHOD FOR CONTROLLING TRAFFIC LIGHT - A traffic light control apparatus and method is provided. The traffic light control apparatus for controlling an emergency vehicle in a traffic network includes: a traffic network control unit configured to determine overall traffic network control and traffic light control for supporting movement of the emergency vehicle during an emergency and transmit a control signal; a traffic light control unit configured to receive the control signal to control a traffic light; and an emergency vehicle control unit configured to transmits a traffic light control mode cancellation request signal to the controlled traffic light.06-10-2010
20100142481APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING SIGNAL FOR HANDOFF IN BROADCASTING NETWORK - An apparatus for transmitting a signal for handoff in a transmitter of a broadcasting network where a plurality of center frequencies exist includes: a baseband broadcasting signal generation unit configured to generate a baseband broadcasting signal from broadcasting data to be transmitted; a transmitter identification signal sequence generation unit configured to generate a transmitter identification signal of the transmitter; a first transmission unit configured to combine the baseband broadcasting signal and the transmitter identification signal, and up-convert the combined signal to a center frequency of the transmitter; and a second transmission unit configured to modulate the transmitter identification signal, and up-convert the modulated transmitter identification signal to center frequencies of adjacent transmitters.06-10-2010
20110103513APPARATUS AND METHOD OF MULTI-ANTENNA TRANSMITTING FOR TERRESTRIAL DTV BROADCASTING SIGNAL AND ADDITIONAL DATA - Provided is a transmission apparatus and method for a terrestrial digital TV (DTV) broadcast and additional data using a multi-antenna. To transmit additional data inserted in a base band of a terrestrial DTV broadcast signal using a plurality of transmission antennas, the additional data signal may be temporal and spatial encoded or may be temporal and spatial multiplexed, and may be combined with a base band DTV broadcast signal before modulation and thus, a transmission efficiency of the additional data may increase without affecting a performance of an existing terrestrial DTV broadcast receiver.05-05-2011
20110103514TRANSMITTER/RECEIVER AND DATA TRANSMISSION/RECEPTION METHOD IN COMMUNICATION SYSTEM - A transmitter for transmitting data in a communication system includes: a serial/parallel (S/P) conversion unit configured to convert data into an I signal and a Q signal; multiplication units configured to multiply the converted I and Q signals by orthogonal sequences, respectively; conversion units configured to Hilbert-transform the I and Q signals multiplied by the orthogonal sequences; addition units configured to add the I and Q signals multiplied by the orthogonal sequences and the Hilbert-transformed Q and I signal, respectively; and an intermediate frequency (IF)/radio frequency (RF) unit configured to up-convert the added I signal and the added Q signal and transmit the converted I and Q signals.05-05-2011
20110107189APPARATUS AND METHOD FOR TRANSMITTING DATA IN COMMUNICATION SYSTEM - An apparatus for transmitting data in a communication system includes: a first repeater configured to repeat information bits of data to be transmitted a first repetition number of times; an interleaver configured to interleave the information bits repeated the first repetition number of times; an accumulator configured to accumulate-code the interleaved information bits; a second repeater configured to repeat the accumulate-coded information bits a second repetition number of times; a puncturer configured to puncture the information bits repeated the second repetition number of times; and a P/S converter configured to convert the punctured information bits and the information bits of the data and output RA-coded information bits.05-05-2011
20110151778RANGING UP-SIGNAL PRE-DISTORTION SYSTEM AND METHOD - Provided is a ranging up-signal pre-distortion system and method. The ranging-up signal pre-distortion system may include a channel gain estimator to estimate a channel gain based on a down-signal, and a signal distortion unit to distort a ranging up-signal based on the estimated channel gain.06-23-2011
20110151809APPARATUS AND METHOD FOR ANALYZING CHANNEL USING TRANSMITTER IDENTIFICATION SIGNAL - Provided is a channel analysis apparatus and method using a transmitter identification signal. The channel analysis apparatus using the transmitter identification signal may include a reference signal generating unit to generate a reference signal, a correlation unit to correlate a received signal and the reference signal to calculate a correlation value, an interpolation unit to interpolate the calculated correlation value, and an analysis unit to analyze the received signal using the interpolated correlation value.06-23-2011
20110234901APPARATUS AND METHOD FOR CONTROLLING INFRASTRUCTURE BASED ON BROADCASTING SIGNALS - An apparatus for transmitting broadcasting content including a control signal in a broadcasting network, the apparatus includes: a modulator configured to modulate broadcasting content by a predetermined modulation method; a control signal generator configured to generate a control signal for remote control of infrastructure; an adder configured to add the control signal to the modulated broadcasting content; and a DTV transmitter configured to convert the added signal to a DTV broadcasting signal and transmit the DTV broadcasting signal.09-29-2011
