Abstract:
PURPOSE: A collaboration paring method and a mobile device using the same are provided to make collaboration between mobile devices which move in the same way. CONSTITUTION: First motion of a first mobile device is sensed(S230). Information about second motion of a second mobile device is received from the second mobile device(S280). It is determined whether the first motion is matched with the second motion. If the first motion is matched with the second motion, the mobile device is registered as a cooperator(S290,S300).
Abstract:
다중통신프로토콜및 준직교시공간블록부호지원가능한 MIMO 통신시스템의가변형심볼검출방법이제공된다. 본발명의실시예에따른심볼검출방법은, 입력신호를다중통신프로토콜에서정의하는전송행렬및 해당 MIMO 전송모드에맞게단일하드웨어로심볼검출가능하도록재정렬하고, MIMO 저농모드에맞게설정된입력값을이용하여파라미터를계산한다. 이에의해, 각기다른전송행렬에대해서단일하드웨어로심볼검출이가능하게함으로써하드웨어복잡도감소및 다중통신프로토콜에대한유연성을확보하고, QO-STBC 부호에대한심볼검출에대한하드웨어복잡도증가문제를해결할수 있게된다.
Abstract:
PURPOSE: A method for securing a witness is provided to immediately and conveniently secure an accident witness by building a database of information about witnesses around the accident scene. CONSTITUTION: A first vehicular telecommunication tool(110) transmits an accident signal to an infra(120). The infra transmits an accident signal to a second vehicular telecommunication tool. An identity validation information of a second vehicular telecommunication tool(130) connected to the infra is collected. The collected identity validation information is stored in a server to build a database.
