摘要: Disclosed herein is an apparatus and method for providing composite sensor information. The apparatus receives sensor information from a plurality of sensors and creating a virtual sensor as a proxy for a plurality of effective sensors included in a region requested to be searched from a user terminal. Thereafter, the apparatus creates composite sensor information by fusing a plurality of the sensor information corresponding to the plurality of effective sensors included in the virtual sensor.

摘要: Provided is a channel estimation method and device in a wireless communication system. A channel estimating device for estimating a channel based on a received signal generates an initial channel estimate by using a preamble extracted from the received signal, and determines whether there is a midamble between data symbols appearing next to the preamble. When there is a midamble, the channel estimating device acquires a first channel estimate by using the midamble, and acquires an updated second channel estimate by using the initial channel estimate and the first channel estimate. The channel estimating device performs channel equalization with the second channel estimate to compensate distortion.

摘要: A method for a first mobile station to transmit a safety message to a second mobile station is provided. The first mobile station competitively transmits a non-safety message to the second mobile station during a first period. The first mobile station spreads a safety message and generates a spread message when a second period starts, and transmits the spread message to the second mobile station. Accordingly, safety message transmission delay or data loss in the inter-vehicle communication can be prevented.
