20090158131 | VITERBI DECODING APPARATUS AND METHOD - A Viterbi decoding apparatus receives a plurality of block data in time order, and transmits a block data group including the plurality of block data. Then, the Viterbi decoding apparatus applies a Viterbi decoding algorithm to the block data group and outputs some block data of the block data group. In this way, it is possible to provide a Viterbi decoding apparatus that can operate at a high speed and improve a data transmission rate. | 06-18-2009 |
20100142596 | SYNCHRONIZATION ERROR TRACKING DEVICE AND METHOD THEREOF - Provided is a synchronization error tracking device and method. The method and system estimates and corrects the synchronization error generated by time and frequency offsets during the data transmission interval and uses a module designed for initial synchronization or channel estimation without adding a new correlation operator. Further, a combining mark value and a synchronization position value acquired during the synchronization process are used. | 06-10-2010 |
20110051746 | METHOD AND APPARATUS FOR GENERATING DATA FRAME, AND METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING DATA FRAME IN WIRELESS COMMUNICATION SYSTEM - A method for generating a data frame in a wireless communication system includes generating a plurality of first headers having information about the number of segments of a payload, generating a plurality of second headers having information about a transmission mode and a length of predetermined segments among segments of the payload, generating a third header having a transmission mode and a length of remaining segments of the payload; generating a fourth header having supplementary information of the payload and error information of the supplementary information and the first to third headers or error information of the supplementary information and the third header; and generating a data frame with the first to fourth headers sequentially allocated. | 03-03-2011 |
20120007855 | CONVERTING METHOD, DEVICE AND SYSTEM FOR 3D STEREOSCOPIC CARTOON, AND RECORDING MEDIUM FOR THE SAME - Disclosed herein are a method and a system for stereoscopic three-dimensional (3D) cartoon conversion and a recording medium for the same. In accordance with the method and the system for stereoscopic 3D cartoon conversion and the recording medium for the same, a two-dimensional (2D) digital still image and an alpha map image including depth information are received, and a depth information range, absolute binocular parallax, relative binocular parallax and a screen position are simultaneously controlled based on the depth information included in the alpha map image and a user input, thereby generating a stereoscopic 3D cartoon. Accordingly, it is possible to maximize productivity as compared to a manual operation. | 01-12-2012 |
