Abstract
Disclosed herein are a system, non-transitory computer-readable medium, and method for encoding and decoding information on a data bearing medium. A message comprising a bit string is read. A plurality of substrings in the message may be associated with a phase invariant codeword.
Claims15
A method of encoding a message, comprising:
- reading a message comprising a bit string of a first length;
- dividing the message into a plurality of substrings, each substring having a second length shorter than the first length;
- determining a phase invariant codeword associated with each substring;
- and,
- generating a composite codeword comprising each phase invariant codeword.
2 more elements
A non-transitory computer-readable storage medium storing instructions that when executed by a processor, cause the processor to:
- divide a bit string message of a first length into a plurality of substrings of a second length;
- for each substring, select, from a number of groups of phase invariant codewords having different properties, a group of phase invariant codewords having a particular property;
- and,
- from each selected group, select a phase invariant codeword associated with the substring for which the group was selected.
