Code-word i.e. data code-word, iterative-decoding method for e.g. wireless mesh communication system, involves comparing symbols of code-word with symbols of copies, and repeating construction stage when compared symbols are not identical

摘要

The method involves constructing a resulting code-word associated to number of erasures when a number of erasures associated to another code-word is higher than capacity correction of a predetermined code. The former code-word is decoded, and symbols of the decoded code-word are compared with symbols of copies of the code-word. The decoded code-word is used as an output when compared symbols are identical. The construction stage is repeated by varying positions and/or values of symbols marked as non-erasure when the symbols are not identical, and decoding and comparison stages are repeated. Independent claims are also included for the following: (1) a computer program product comprising a set of instructions for implementing a code-word iterative-decoding method (2) a storage medium comprising a set of instructions for implementing a code-word iterative-decoding method (3) a code-word decoding device comprising a resulting code-word constructing unit.
