Abstract
In general, techniques are described for coding data defining a sequence using one-to-one codes. An apparatus comprising a processing unit and a storage unit may implement the techniques. The processing unit decodes the index using a combinatorial enumeration process to generate a sequence. The index identifies the sequence in an array of all possible sequences ordered according to probabilities of the possible sequences assuming the possible sequences are produced by a memoryless source. The combinatorial enumeration process reorders sequences from the memoryless source according to the corresponding probabilities. The storage unit stores the sequence.
