Abstract:
A first message, associated with going from one of a plurality of variable nodes to one of a plurality of check nodes is computed, wherein: (1) one or more connections between the plurality of variable nodes and the plurality of check nodes are specified by an LDPC parity check matrix and (2) a scaling constant is used to compute the first message. A second message, associated with going from one of the plurality of check nodes to one of a plurality of variable nodes, is computed, wherein the scaling constant is not used to compute the second message.
