摘要： A hierarchical modulation device modulates a plurality of first hierarchical symbols according to a first modulation method to generate a plurality of first hierarchical modulation symbols, inserts a plurality of pilot symbols into a plurality of second hierarchical symbols to generate a plurality of pilot insertion symbols, modulates a plurality of pilot insertion symbols according to a second modulation method to generate a plurality of second hierarchical modulation symbols, and maps a plurality of first hierarchical modulation symbols and the plurality of second hier archical modulation symbols in the signal space to generate a plurality of hierarchical modulation symbols. Therefore, the hierarchical modulation device can improve receiving performance of the enhancement layer without influencing the base layer.

摘要： The present invention relates to a channel encoder for an enhancement layer of a digital-multimedia-broadcasting transmitting device, a digital broadcasting transmitting device, a digital broadcasting receiving device, and an extension structure of sub-channel configuration field (FIG0/1 ) for designating a protection level of sub-channel at the enhancement layer. In a channel encoder for the enhancement layer according to the invention, the channel encoder is included in a hierarchical DMB transmitting unit that modulates a base layer transport stream and a enhancement layer transport stream for video and audio by a base layer modulation system and an enhancement layer modulation system, respectively, and performs symbol mapping of the enhancement layer according to the position of a constellation based on the base layer modulation system. Furthermore, the hierarchical DMB transmitting unit includes an energy dispersal scrambler that disperses energy of the enhancement layer transport stream, and a turbo encoder that receives a double-binary input vector corresponding to an output of the energy dispersal scrambler and encodes it by using a double-binary circular recursive systematic code.
