  • Abstract
    This paper presents the soft-input soft-output (SISO) linear programming (LP) decoder. It is shown that the soft information gleaned from a pseudo-codeword solution to the LP optimization is not only useful, but that it can be superior to the soft information output from a SISO belief propagation (BP) decoder in certain situations.
