1. A method for processing data generated in compliance with a Data Over Cable Service Interface Specification (DOCSIS) standard, for satellite communication, comprising:

  • (1) receiving DOCSIS-compliant data encoded with a Reed-Solomon encoding scheme;

    (2) turbo-encoding the DOCSIS-compliant data using an integrated circuit having a turbo encoder circuit;

    (3) generating baseband-frequency in-phase and quadrature-phase components of the turbo-encoded DOCSIS-compliant data;

    (4) interpolating the baseband-frequency in-phase and quadrature-phase components to a common sample rate that is higher than a plurality of DOCSIS-compliant bandwidth sample rates;

    (5) digitally pre-compensating the common sample rate baseband-frequency in-phase and quadrature-phase components for impairments encountered in one or more subsequent processes;

    (6) converting digitally pre-compensated common sample rate baseband-frequency in-phase and quadrature-phase components to one or more analog signals; and

    (7) up-converting the one or more analog signals to a satellite frequency signal.
