    摘要： The invention relates to a serrated cutting tip and a serrated cutting tool having the cutting attached thereto capable of working a work piece at a fixed workability. The cutting tip includes a bond layer, which has super abrasive particles contained therein and grooves formed on a face which is in contact with the work piece, and a blank layer for strongly supporting the bond layer, by which a working plane of the cutting tip contacting the work piece is uniformly maintained during working use and debris can be readily discharged. As a result, workability is improved and lifetime is prolonged.

    摘要： A digital television (DTV) transmitting system includes a first frame decoder, a second frame decoder, and a frame multiplexer. The first frame decoder forms first enhanced data frames, encodes each data frame for error correction, forms a first super frame by combining the encoded first frames, and interleaves the first super frame. The second frame decoder forms second enhanced data frames, encodes each data frame for error correction, forms a second super frame by combining the encoded second frames, and interleaves the second super frame. The frame multiplexer multiplexes the interleaved first and second enhanced data frames.

    摘要： A digital television transmitting system includes a pre-processor, a packet generator, an RS encoder, and a trellis encoder. The pre-processor pre-processes enhanced data by coding the enhanced data for first forward error correction and expanding the FEC-coded enhanced data. The packet generator generates enhanced data packets including the pre-processed enhanced data and main data packets and multiplexes the enhanced and main data packets. Each enhanced data packet includes an adaptation field in which the pre-processed enhanced data are inserted. The RS encoder performs RS encoding on the multiplexed data packets for second forward error correction, and the trellis encoder performs trellis encoding on the RS-coded data packets.

    摘要： A channel equalizer includes an overlap unit, an estimator, a calculator, a compensator, and a save unit. The overlap unit overlaps a group of data packets in a broadcast signal. The group data packets include a head, a body, and a tail, and a known data sequence is periodically included in the body. The estimator estimates a CIR of each data region the body using the known data sequence, and it further estimates CIRs of data regions in the head or tail using the CIRs obtained for the data regions in the body. The calculator calculates equalization coefficients based on the CIRs estimated by the estimator, and the compensator compensates channel distortion of the overlapped data using the equalization coefficients. The save unit saves the compensated data.

    摘要： A DTV receiver includes a tuner, a demodulator, a known sequence detector, and a frequency domain equalizer. The tuner initially receives a broadcast signal including valid data in which a known data sequence is periodically repeated. The demodulator demodulates the broadcast signal, and the known sequence detector detects the known data sequence from the demodulated signal. The frequency domain equalizer compensates channel distortion of the demodulated broadcast signal in a frequency domain using the detected known data sequence. In addition, the DTV receiver may further include a time domain equalizer which compensates channel distortion of the time domain signal, or a noise canceller which removes a predicted noise from the time domain signal.

    摘要： A DTV transmitter includes a pre-processor pre-processing supplemental data, a multiplexer multiplexing pre-processed data with main data, and a byte-symbol converter converting each data byte of the multiplexed data into a symbol. It further includes a symbol processor processing each supplemental data symbol outputted from the byte-symbol converter. It encodes one of upper and lower bits of each supplemental data symbol into first and second data bits, post-decodes the first data bit, and outputs the post-decoded data bit and the second data bit as a symbol. The DTV transmitter further includes a symbol-byte converter converting each symbol outputted from the symbol processor into a data byte.
