Abstract:
A device for authenticating electronic toll collection process and an electronic toll collection system using the same are provided to process authentication of the vehicle based on unique vehicle data to prevent illegal usage such as exchange of a smart card or an OBE(OnBoard Equipment). A user authentication information storing module(210) stores authentication information of a vehicle user. Whenever vehicle authentication is needed, an onboard electronic toll collecting module(220) receives unique vehicle ID information through the vehicle network, reads the authentication information of the vehicle user from the user authentication information storing module, generates the authentication data based on the unique vehicle ID data and the user authentication information, and transmits the authentication data to the outside. The onboard electronic toll collecting module stores ID information of the onboard electronic toll collecting module when the authentication data is generated. The user authentication information storing module includes billing information for collecting an electronic toll.

Abstract:
A method for recovering and tracking a timing using a correlation value estimation window and a computer-readable medium having the program performing the functions embodying the same are provided to accurately recover and track the timing by changing the correlation value estimation window or a threshold value according to channel characteristics. An upper position and a lower position of a correlation value estimation window are limited to include a symbol position with a large correlation value based on a window of a preamble field(S110). The correlation value is checked after an upper limit of the correlation value estimation window reaches on a window corresponding to the preamble field, an FSW(Frame Start Word) field, or a CSW(Channel Start Word) field. It is determined whether the correlation value extends a threshold value(S120). When the correlation value is greater than the threshold value, the upper and lower limits of the correlation value estimation window are updated, and the next window is calculated(S130).
Abstract:
An MOST(Media Oriented Systems Transport) gender and an MOST network using the gender are provided to use an MOST device by connecting a UTP(Unshielded Twisted Pair) cable when usage of a POF(Plastic Optical Fiber) used for configuring a network of the MOST device is restricted, thereby reducing an MOST network configuration cost. An O/E(Optical Electro) converter(210a) converts an optical signal which is a transmission signal of an MOST device(100) into an electric signal to send the signal through an electric cable. An E/O(Electro Optical) converter(210b) converts an electric signal into an optical signal for a receiving signal of the MOST device. A connector interface(220) sends the converted electric signal by connecting with the electric cable, and outputs the electric signal received from the electric cable to the E/O converter to input the outputted signal as the receiving signal of the MOST device.

Abstract:
A real-time traffic information collecting method using wireless communication and a system therefore are provided to check out the accident or road states of an area positioned out of a communication range of an RSE(Road-Side Equipment), by using the communication between OBEs(On-Board Equipment) and between the OBE and a sensor. A real-time traffic information collecting method using wireless communication, especially using communication between an RSE(200,210) installed at the road side and an OBE installed in a vehicle, is composed of a step of for transmitting the state information of a first vehicle(300) positioned in a shadow region(110) out of a communication coverage region(120) formed between the RSE and the OBE, from a first OBE(400) installed in the first vehicle to a second OBE(410) installed in a second vehicle(310) passing by the first vehicle, and a step of transmitting the state information of the first vehicle to the first RSE through the second OBE when the second vehicle reaches a communication coverage region.
Abstract:
PURPOSE: An MAC(Media Access Control) processing device is provided to process data of downstream channels as simultaneously extracting overhead information, and to process an AAL5 in software, then to process ATM cells only in hardware, thereby updating exact slot counters and simplifying hardware. CONSTITUTION: An ESF(Extended Super Frame) buffer(102) generates an OH bit from an input bit stream. A bit2byte block(106) removes the OH bit from the supplied bit stream, and processes the bit stream in byte units. An HEC REC block(122) recovers or senses an error of an ATM cell. An ATM filter(124) separates unnecessary ATM cells. A synchronization block(104) adjusts frame synchronization. A scheduler(136) schedules data transmissions of upstream channels by using slot counter information and upstream channel control information. A CRC6 block(112) senses whether an error is generated from a frame. A receive connection buffer(132) extracts the upstream channel control information. A connection table(138) stores necessary information. A read controller(142) reads data to be transmitted to an upstream channel. A head adder(144) and an HEC block(146) configure ATM headers, and generate ATM cells. A ranging block(154) informs of starting time for transmitting data to the upstream channel. A de-interleaver block(108) restores interleaved data to original data.
