摘要： The present invention provides a coding device of a low-density parity-check (LDPC) code for simply coding information data without generating a code generator matrix. The coding device forms a parity-check matrix having two sub-matrixes. At this time, the first sub-matrix is a random matrix or a structural matrix. The second sub-matrix is a structural matrix having two 1s in each column. Parity data is calculated by using the structural second matrix without calculating an inverse matrix of the second matrix when temporary data is generated by using the first sub-matrix with reference to the information data. Code data is generated from the parity data and the information data and is transmitted.

摘要： The present invention relates to a transmitter in an OFDM system for improving the PAPR, and a method thereof. According to the exemplary embodiment of the present invention, channel encoding is performed in order to correct a data transmission error of a radio channel, a predetermined bit of the channel encoded data is bit-inverted by using a mask bit or a mask bit sequence, and a PAPR of the signal is reduced. Accordingly, reduction of transmission efficiency which has been generated in block coding and DSI methods is not generated when the signal is transmitted because an additional bit is not required.

摘要： Embodiments relate to a single poly type EEPROM and a method for manufacturing an EEPROM. According to embodiments, a single poly type EEPROM may include unit cells. A unit cell may include a floating gate at a side of a control node formed on and/or over a semiconductor substrate having an activation region and a device isolation area, not overlapping a device isolation region but overlapping only a top of the activation region. A select gate may be formed on and/or over a top of the activation region. According to embodiments, a ratio of a capacitance of a control node side to a capacitance of a bit line side may increase, which may improve a coupling ratio. According to embodiments, a junction capacitance may be maximized by not doping the floating gate with an impurity, which may allow for a reduction in chip size by securing design margins.
