  • Patent number: 8135095
    Abstract: An enhanced VSB receiver includes a tuner which tunes an RF signal and converts it into an IF signal, an IF mixer which converts the IF signal into a baseband signal, and a demodulator which demodulates the baseband signal into a VSB signal. The enhanced VSB receiver further includes a map recovery unit which recovers VSB map information of the VSB signal, an enhanced equalizer for compensating channel distortion of the VSB signal and outputting an equalized symbol, and an enhanced Viterbi decoder for estimating whether polarity inversion occurred during a symbol period of the equalized symbol and Viterbi-decoding the equalized symbol based on the polarity estimation.

  • Publication number: 20060172104
    Abstract: The present invention is to improve application of an adhesive sheet by imparting air vent channels to an adhesive surface of the sheet. According to the present invention, air vent channels are formed to have various heights and widths so that the respective air vent channels can be vanished at certain time intervals, thereby facilitating removal of air and increasing an adhesion area to shorten time required for obtaining a designed adhesive force, and the increase of the adhesion area improves smoothness between an adhesive surface and a target surface so that patterns of the air vent channels cannot emerge on a front surface of the sheet.
