초록 ▼

Apparatus for decoding an input digital signal by replacing successive n-bit groups of the input digital signal with respective ones from an ensemble of m-bit data words, each m-bit data word having an associated n-bit code word, where n is greater than m, comprises: means for determining the Hamming distance between an n-bit group of the input digital signal and each of the n-bit code words associated with the ensemble of m-bit data words; and means for replacing that n-bit group of the input digital signal with an m-bit data word from the ensemble of m-bit data words for which the Hamming distance between the n-bit code word associated with that m-bit data word and that n-bit group is the lowest.

대표청구항 ▼

Apparatus for decoding an input digital signal comprising successive n-bit groups of data bits by replacing said successive n-bit groups with respective ones from an ensemble of m-bit data words, each said m-bit data word having at least one associated valid n-bit code word, where n is greater than m, said apparatus comprising: means for determining a Hamming distance between a current n-bit group of said input digital signal and each of said valid n-bit code words; means for detecting whether one or more of said valid n-bit code words each have the lowest Hamming distance from said current n-bit group; means, responsive to a detection that only one of said valid n-bit code words has the lowest Hamming distance from said current n-bit group, for replacing said current n-bit group with an m-bit data word from said ensemble of m-bit data words for which said Hamming distance between a valid n-bit code word associated with said m-bit data word and said current n-bit group is the lowest; and means, responsive to a detection that more than one of said valid n-bit code words have said lowest Hamming distance from said current n-bit group, for replacing said current n-bit group with an m-bit data word associated with one of said more than one valid n-bit code words having said lowest Hamming distance from said current n-bit group when said lowest Hamming distance is equal to one and for replacing said current n-bit group with an m-bit data word for which a bit separation between a valid n-bit code word associated with said m-bit data word and said current group is the lowest when said lowest Hamming distance is not equal to one.
