摘要:
A mobile terminal and a method of displaying an object related information in the mobile terminal are disclosed, in which the method includes receiving an image via a camera module of the mobile terminal, the received image depicting objects located within a predetermined distance from the mobile terminal, obtaining at least one object related information corresponding to the received image, displaying the received image including the obtained at least one object related information, receiving a zoom-in command signal for the camera module, zooming in on the displayed image according to the received zoom-in command signal such that the zoomed-in image is displayed at a zoom position, and displaying object related information in the obtained object related information corresponding to at least one object of the zoomed-in image depicted between the zoom position and the predetermined distance.

An apparatus and method for recording and/or reproducing data on a disc are provided using padding information, and a corresponding information storage medium. The recording method includes recording a recording unit block in which invalid data is padded in part of the block and recording padding information indicating that the invalid data is included. According to the method, a disc drive becomes able to distinguish valid data from invalid data in an error correction block such that reliability of reproduction increases and stability of the system is improved.
摘要:
Methods and apparatus for constructing a parity check matrix for use in a low-density parity check (LDPC) coding scheme are provided. The apparatus includes at least one index generator for generating row indexes of “1”s, which indicate row positions of the “1”s in each column of the parity check matrix, wherein the index generator is implemented by a modular shift register generator that generates a row index of a “1” at each clock.

摘要:
A soft demodulation method and apparatus including calculating partial sums for a unit of each predetermined number of bits of a codeword received from a channel; calculating a value of each entry of the decoding table by referring to the partial sums; and detecting a maximum among values of all entries of the decoding table and calculating a log-likelihood ratio (LLR) using the detected maximum. Accordingly, it is possible to reduce the amount of computation required to perform a soft demodulation process using run-length limited (RLL) codes and to simplify the soft demodulation process.
摘要:
A method of converting a parity check matrix for low density parity check coding comprising moving rows and columns of the parity check matrix such that the parity check matrix includes a lower triangular submatrix. A calculation load for creating parity information can be reduced by using the converted parity check matrix including the lower triangular submatrix.
