摘要： A method and apparatus for synchronization of a moving picture experts group (MPEG) transport stream, which minimizes an initial delay are provided. A packet synchronization unit and a mode of the packet synchronization unit to are initialized to “0”. Values of sync words are stored by shifting values of a sync word register when the sync words have been received and the received sync word is compared with predetermined code words As a result of the comparison, a determination is made as to whether a bit difference between the sync words and the predetermined code words exceeds a predetermined threshold value. A verification is then made as to whether all bits of the sync words correspond to all bits of the predetermined code words, when it is determined as a result of the determination that the bit difference is less than or equal to the predetermined threshold value and the MPEG transport stream is descrambled before returning to step of storing values of sync words by shifting values of a sync word register.

摘要： A method and apparatus for performing channel compensation and symbol demodulation using an estimated channel impulse response during coherent demodulation of a received Orthogonal Frequency Division Multiplexing (OFDM) signal are provided. In the apparatus, an FFT processor IFFT-processes a received signal. A channel compensator generates a channel-compensated signal by multiplying the FFT received signal by an estimated channel impulse response and calculates the power of the estimated channel impulse response. A symbol demodulator sets the power of the estimated channel impulse response as a reference point defining a minimum distance between signal points in a signal constellation, and decides soft metric values for channel decoding using the reference point and I-channel and Q-channel signal components of the channel-compensated signal. A decoder recovers information bits by decoding the soft metric values.

摘要： Field emission nanostructures assist operation of a microdischarge device. The field emission nanostructures are integrated into the microdischarge device(s) or are situated near an electrode of the microdischarge device(s). The field emission nanostructures reduce operating and ignition voltages compared to otherwise identical devices lacking the field emission nanostructures, while also increasing the radiative output of the microdischarge device(s).

摘要： An apparatus and method for decoding low density parity check (LDPC) codes are provided. A memory module configured by a plurality of unit memories stores a reliability value. Variable node processors perform a computation associated with a variable node, and update data of the memory module in a column direction, respectively. Check node processors perform a computation associated with a check node, and update data of the memory module in a row direction, respectively. A parity checker determines if all errors have been corrected such that an iterative decoding process is performed. A memory access control module selects a unit memory to be updated by a variable node processor or a check node processor.
