DECODING METHOD AND DECODING DEVICE

摘要

Embodiments of the present invention provide a decoding method and device, capable of reducing the rate of output bit error with simple decoding, thus enhancing the anti-jamming capability of the system. The method comprises: performing iterative decoding on multidimensional codes to obtain uncorrectable code words, the number of error bits of code words in each dimension where error bits of the uncorrectable code words are located being larger than the capacity of the multidimensional codes; determining the location of error bits of uncorrectable code words obtained through iterative decoding on the multidimensional codes, wherein the location of error bits in the uncorrectable code words is the multidimensional coordinate location of the error bits in the multidimensional codes; correcting error bits of part of the uncorrectable code words in the multidimensional codes based on the determined location of error bits in the uncorrectable code words, such that the number of error bits of code words in each dimension where the error bits of the uncorrectable code words are located is smaller than the capacity of the multidimensional codes; after correcting the error bits of part of the uncorrectable code words in the multidimensional codes, performing iterative decoding on the multidimensional codes wherein the number of error bits of code words in each dimension where the error bits of the uncorrectable code words are located is smaller than the capacity of the multidimensional codes. The embodiments of the present invention are applicable to the field of decoding technology.
