Query: Numerical Issues Affecting LDPC Error Floors   Numerical issues related to the occurrence of error floors in floating-point
simulations of belief propagation (BP) decoders are examined. Careful
processing of messages corresponding to highly-certain bit values can sometimes
reduce error floors by several orders of magnitude. Computational solutions for
properly handling such messages are provided for the sum-product algorithm
(SPA) and several variants.
