1. An article of manufacture comprising a non-transitory machine-readable medium, having thereon stored in non-transitory form instructions adapted to be executed by a processor, which instructions when executed by said processor result in a process of removing carrier signal independent data from a digital sample stream, comprising:

  • receiving a digital sample stream encoded with carrier signal independent data;

    using linear predictive coding calculations to identify signal components of said digital sample stream; and

    extracting carrier signal independent data from said digital sample stream.
