    摘要: Provided are a system and method for informing a vehicle accident using a telematics device. In an emergency, such as vehicle collision, etc., the system and method propagate information on the accident to vehicles around the accident scene, thereby informing the vehicles of traffic congestion. Since the vehicles continuously inform the same to vehicles behind through ad-hoc communication, a vehicle guided by a telematics device can recognize the traffic congestion ahead, re-search for a path, and thereby make a detour. Therefore, although vehicles behind the accident scene cannot see the occurrence of the accident on a foggy highway, etc., the risk of a chain-reaction crash is reduced. In addition, it is possible to avoid traffic congestion due to an accident in downtown.

    摘要: A constant amplitude decoding apparatus and method for multiplexed direct-sequence spread spectrum communication system are provided. The constant amplitude decoding apparatus includes: a despreading and demultiplexing module receiving a data stream of a constant amplitude and despreading and demultiplexing the received data stream to restore it to a 2D signal; a decoding module first performing a vertical decoding on the 2D signal and then performing horizontal decoding thereon; a control module determining whether to repeatedly perform vertical decoding and horizontal decoding; and a bit stream information output module outputting the decoding results from the decoding module as a bit stream.
