    • A high speed input buffer device for a turbo decoder and an input method thereof are provided. The input buffer device comprises a combing buffer for outputting stored symbols based on read addresses; a write MUX for dividing the output symbols into systematic, parity-1, and parity-2 symbols based on a BitSel signal, and outputting the divided symbols, first and second de-first rate matchers for individually performing a de-first rate matching operation with respect to the parity-1 and parity-2 symbols output from the write MUX, a data conversion unit generating code words, each of which contains a systematic symbol, a parity-1 symbol, and a parity-2 symbol, by using the systematic symbols output from the write MUX and the de-first-rate-matched parity-1 and parity-2 symbols, an input buffer unit having a double buffer structure, containing code blocks corresponding to the plurality of turbo decoders, storing each of the code words in a memory area of a code block corresponding to a decoder distinction signal which represents one of the turbo decodes, and outputting the stored code words to relevant turbo decoders, and a buffer controller for providing the input buffer unit with the decoder distinction signal, and providing the write MUX with the BitSel signal for dividing the output symbols into systematic, parity-1, and parity-2 symbols. Since the number and the area of memory elements required for the input control for a decoder are reduced, processing time, the error occurrence rate upon realizing the chip, and power consumption can be reduced.
