LDPC LDPC DECODER WITH A VARIABLE NODE UPDATER WHICH USES A SCALING CONSTANT

摘要

Between it is the first message relating to proceed to one of a plurality of check nodes is calculated from one of a plurality of variable nodes, (1) a plurality of check nodes and a plurality of variable nodes being defined by one or more connections are the LDPC parity check matrix, (2) scaling constant is used to calculate a first message. A second message associated with one of a plurality of variable nodes proceeding from the one of the plurality of check nodes is calculated, and the scaling constant is not used to calculate the second message. ;
