摘要:
A method for transmitting a signal in a wireless communication system. The method comprises the steps of: grouping two subcarriers having different channel characteristics; identifying a number of all cases occurring when either equal symbols or different symbols, among symbols determined upon applying a first modulation scheme, are mapped to the two subcarriers; and mapping two subcarriers corresponding to each of the number of all cases to one symbol according to a second modulation scheme, and transmitting the signal, wherein a modulation order of the second modulation scheme is two times higher than a modulation order of the second modulation.

The present invention is directed to a video unified codec device and its method. According to an embodiment of this invention, the unified codec device comprises parsing and decoding functional units (PD FUs) extracting and grouping context information, control signals, and data in bit streams inputted according to different syntax data per codec, macro-block-based functional units (MB-based FUs) unified based on block-based process units of each codec, for decoding data outputted from PD FUs, and a global control unit (GCU) for controlling MB-based FUs grouped after corresponding control signals and context information received from PD FUs to each codec and processing. By this invention, a new concept and structure of unified codec corresponding to similarities, differences, and considerations between different codecs can be presented.
摘要:
A method of manufacturing a transmission electron microscope inspection sample. The sample is mounted into a recess in the mount and the sample is grinded to a preset target thickness. A recess for mounting the sample and a groove for separating the sample from the recess are formed on a top surface of the mount. The sample is fixed into the recess using mounting wax. The protruding portion of the sample protrudes above the mount and is grinded by the grinder. The depth of the recess is based on the target thickness of the sample. The protruding portion of the sample is grinded to the top surface of the mount.

Provided are bitstream encoding/decoding methods and devices. The decoder includes: a condition information extracting unit creating recognition information using syntax tree information indicating a hierarchical structure between syntax elements corresponding to bits of an input bitstream, respectively and rule description information indicating connectivity between the syntax elements; and a decoding unit decoding data contained in the bitstream into moving image data using the recognition information. Accordingly, it is possible to decode bitstreams encoded in a variety of types (syntax, semantics) corresponding to a variety of standards (for example, MPEG-1, MPEG-2, MPEG-4, and MPEG-4 AVC) by the use of the same information recognition method.
摘要:
A stand device for a mobile terminal is provided. The device includes a body and at least one slope unit. The body has a seat and a lower side. The seat seats the mobile terminal thereon. The lower side of the body is curved so that the body may be tilted. The at least one slope unit tilts the body in a relevant direction by moving a center of mass.

Disclosed are a bitstream decoding device and a method thereof. The decoding device includes a toolbox, configured to include a plurality of functional units which independently perform a predetermined process—each of the functional units is distinguished by using unique identifiable information; and a connection control unit, configured to selectively load at least one functional unit by using the identifiable information and to control a bitstream to be decoded as video data. With the present invention, it is possible to decode bitstreams, encoded in various ways according to each standard, by using the same information recognizing method.
