Abstract:
1. A decoder device for decoding packet signals composed of control codes and data codes, the control codes including a specified combination of a modulation formula and a coding rate for decoding the data codes, the decoder device comprising: means for dividing the packet signals into the control codes and the data codes; means for decoding the control codes and for decoding the data codes based on a plurality of combinations, each combination consists of a modulation formula and a coding rate, thereby generating a plurality of data signals decoded based on the respective combinations; and means for selecting a decoded data signal, from among the plurality of decoded data signals, that is decoded based on a combination which coincides with the specified combination included in the control codes, thereby outputting the selected data signal therefrom; wherein the decoding means includes: a plurality of demodulators, the number of which corresponds to the number of the modulation formulae; a plurality of de-interleavers, each connected to each demodulator; and a plurality of decoders for outputting decoded data signal outputs, each decoder outputting a plurality of decoded data signal outputs, the number of which corresponds to the number of coding rates.
