Abstract
Decoding by passing messages back and forth between a set of variable nodes and a set of check nodes, where at least one of the nodes broadcasts the same message to each of its associated nodes, is provided. For example, the variable nodes can broadcast and the check nodes can provide individual messages. Alternatively, the check nodes can broadcast and the variable nodes can provide individual messages. As another alternative, the variable nodes and the check nodes can both broadcast to their associated nodes. Broadcasting reduces the number of interconnections required between variable nodes and check nodes. Broadcasting is enabled by providing local storage within the nodes and/or by providing extra processing steps within the nodes.
