| 摘要 |
A method, apparatus and system for channel decoding are disclosed in the embodiments of the present invention. An apparatus for channel decoding comprises: a decoding information acquiring unit, used for acquiring decoding information of a first channel decoding of a data block; a sequence number acquiring unit, used for acquiring, if the decoding result verification of the first channel decoding of the data block fails, a reference sequence number of the data block; a history soft value acquiring unit, used for acquiring at least one matched history demodulation soft value in a history demodulation soft value record table according to the reference sequence number of the data block; a soft value combination unit, used for combining the demodulation soft value of the data block and the at least one matched history demodulation soft value to obtain a combined demodulation soft value of the data block; a second channel decoding unit, used for performing a second channel decoding to the combined demodulation soft value of the data block. A method and system for channel decoding are also disclosed in the embodiments of the present invention. |
