1. A method for decoding data, comprising: receiving a partial set of reliability data over a channel, wherein the partial set of reliability data is associated with a subset of a plurality of variable nodes, and wherein a remaining portion of reliability data not in the partial set of reliability data is corrupted by a condition of the channel; receiving a plurality of variable node values for the plurality of variable nodes; determining processed reliability data for at least the subset of the plurality of variable nodes, wherein the processed reliability data indicates whether reliability data associated with each variable node of the plurality of variable nodes is included in the partial set of reliability data; and updating the plurality of variable node values based on the plurality of variable node values and the processed reliability data, wherein the processed reliability data represents a version of reliability data for at least the subset of the plurality of variable nodes.
