Abstract: The present invention relates to a method of scheduling for an underwater wireless mobile network. Particularly, the present invention relates to a method of scheduling for an underwater wireless mobile network, whereby the method may consider a scheduling method that does not cause collision at a specific time domain, and improve network efficiency by receiving in a sink node a packet in a packet train form in consideration with a transfer velocity of a sound wave and a packet length rather than performing orthogonalization to avoid transmission time overlap at a specific time.

Abstract: The present invention relates to a container search system comprising: a radiation irradiation unit for irradiating radiation to a container to be inspected; a detection unit installed opposite to the radiation irradiation unit to detect radiation having passed through a container; a transfer cart for loading an automobile thereon, on which a container to be inspected is loaded, and travelling along a search path formed between the radiation irradiation unit and the detection unit; and a circulation orbit unit formed to allow the transfer cart to circulate along the search path, wherein a primary side of a linear induction motor for generating a moving magnetic field is formed on either side among the transfer cart and the search path and a secondary-side reaction plate for inducing a secondary eddy current due to the moving magnetic field and generating a linear driving force is formed on the other side thereof. The container search system can transfer a transfer cart according to a linear motor scheme in a radiation search section, and thus can obtain a radiation search image of high quality.

Abstract: Provided is an apparatus for equalizing a channel and determining reception data of a packet communication receiver. The apparatus includes: an input interface unit which receives a reception sample string of a packet having a midamble and location information of the midamble; a sample dividing unit which divides the reception sample string into a first sub sample string and a second sub string stream using the location information of the midamble; and a channel equalizing unit which performs channel equalization on the first sub sample string and the second sub sample string, respectively, using a channel equalizing algorithm of the channel equalizer.
