    摘要: An apparatus and method for transmitting and receiving data having a smallest PAPR in an SLM scheme for PAPR reduction in an OFDM communication system using multiple carriers. To transmit the data having the smallest PAPR, input symbol sequences are duplicated to a plurality of data blocks. Phase-rotated data blocks are generated by multiplying the plurality of data blocks by different phase sequences. Side information for identifying the phase-rotated data blocks is inserted into a predetermined t position of the phase-rotated data blocks. IFFT is performed on the data blocks containing the side information. The data block having the smallest PAPR is selected among the inverse fast Fourier transformed data blocks.

    摘要: A block coding apparatus and method in an OFDM mobile communication system are provided. They reduce PAPR to 3dB or less, while increasing a traditional block coding rate by a factor of 2, by use of complementary sequences. Therefore, spectral efficiency is improved by a factor of 2, maintaining the traditional error correction capability, and thus decoding is facilitated.

    摘要: A multimedia middleware apparatus (513) using metadata, a control method and a storage medium are provided which can receive metadata in multimedia middleware (513) provided in a terminal (510), easily add/delete/change a service, and effectively maintain and manage middleware components. When an open multimedia terminal (510) processes multimedia contents, a multimedia middleware service structure for expressing information of a name, configuration, version and application programming interface, or API, update is configured in the form of metadata. Lists of standard and non-standard services of multimedia middleware are then generated and managed.

    摘要: A method, apparatus and system are provided for controlling a scene structure of a mobile terminal for receiving and displaying data streams in a mobile broadcast system. When logical channels are multiplexed into one physical channel, the multiplexed channels are sequentially decoded and are displayed on a media. A channel circulation scene alternately displays the channels on one media in designated order. In a combination scene structure, a new node is added to a conventional Lightweight Application Scene Representation (LASeR) technology. To compose a scene, fields for time information and scene transition effect are provided. A delay time due to a channel change is reduced. A multi-channel media is effectively provided to address a problem when a user retrieves service content while directly switching a channel. The terminal dynamically composes the multi-channel media using stream source node information from a service provider without an additional mosaic channel.
