摘要： Disclosed herein is a method of providing vehicle wireless communication. In the method, a vehicle receives hand-over-related link information, which includes slot request information about slots requested by a vehicle to a roadside wireless communication device for hand-over of the vehicle, from a central control server. A hand-over preparation message, which includes the hand-over-related link information, is send to a vehicle wireless communication device connected to the vehicle. It is determined that the vehicle completed preparation for performance of the hand-over when a response message to the hand-over preparation message is received from the vehicle wireless communication device. Slots are allocated in consideration of the hand-over-related link information. Beacon frames, which include slot allocation information about the allocated slots, are transmitted to the vehicle wireless communication device. Accordingly, the vehicle wireless communication device and the roadside wireless communication device can reliably perform communication without interruption.

摘要： Disclosed herein is an apparatus for detecting vehicles using laser scanner sensors. The apparatus includes a vehicle location detection unit, a shadow area detection unit, an estimation unit, and a control unit. The vehicle location detection unit detects information about locations and headings of target vehicles located in a local detection area from sensors arranged on the road. The shadow area detection unit calculates shadow areas corresponding to the respective sensors based on the information about the locations of the target vehicles and information about types of the target vehicles. The estimation unit estimates the locations and shadow areas of the target vehicles which will be obtained after a predetermined time has elapsed. When a specific target vehicle tries to enter one of the estimated shadow areas, the control unit outputs a speed control command used to decrease the speed of the specific target vehicle.

摘要： An apparatus for time synchronization of an orthogonal frequency division multiplexing (OFDM) system oversamples a received signal using a master clock having a frequency at least four times higher than a minimum sampling frequency in a transmission apparatus, sets one of a plurality of oversampled signals to an on-time signal, and shifts each of the remaining oversampled signals by a predetermined time on the basis of the on-time signal. The apparatus for time synchronization calculates a correlation value by correlating each of the shifted signals and the on-time signal with a previously known signal, detects a maximum energy value among the calculated correlation values, and detects a start point of a frame by comparing the maximum energy value with a predetermined threshold value.

摘要： A network address translation (NAT) router for connecting an inside network to an outside network. The inside network uses local addresses and has a plurality of voice over Internet protocol (VoIP) systems and a plurality of hosts, and the outside network uses global addresses. An Ethernet driver is connected to Ethernet drivers in the voice over Internet protocol systems by a hub. An Ethernet and Internet protocol (IP) interface module assigns predetermined physical addresses to the Ethernet drivers of the voice over Internet protocol systems. A transmission control protocol/Internet protocol (TCP/IP) module is connected to the Ethernet and Internet protocol interface module and sets a predetermined number of local Internet protocol addresses for the voice over Internet protocol systems. A network address translation module translates an inside local Internet protocol address within a voice over Internet protocol system to a global Internet protocol address.

摘要： A congestion control unit and method in an ATM network is disclosed. The congestion control unit includes a congestion detector, a congestion controller and a routing controller. The congestion detector receives the measured number of cells generated from an output link through an ATM switch module, transmits the measured number of cells to an adaptive connection admission control unit, and detects the state of the output link by use of a utilization of a cell transmission link. The congestion controller receives congestion state information from the congestion detector and receives a cell loss ratio through the ATM switch module. The congestion controller transmits a backward resource management cell to a user or generates a routing control request signal so as to assign the load of the input traffic to another affordable link, and supplies a monitor parameter to the ATM switch module. The routing controller receives the routing control request signal from the congestion controller, and supplies routing information on an affordable link of the same destination to the ATM switch module.
