ABSTRACT:
Methods, algorithms, software, circuits, architectures, and systems for conditionally encoding information and processing conditionally encoded information. The present invention takes advantage of codes where most randomly selected data units fulfill the coding constraints. Thus, only those data units that need encoding (i.e., that do not fulfill coding constraints) are encoded, and those data units that do not need encoding (i.e., that fulfill coding constraints) are not encoded. By doing so, one may increase the density, bandwidth and/or gain of data communications, increase the error checking and/or correcting capabilities of a data communications system, and/or reduce interference in a multi-user system.
