  • Method and system for replica group-shuffled iterative decoding of quasi-cyclic low-density parity check codes
    Publication number: 20080052594
    Abstract: A block of symbols are decoded using iterative belief propagation. A set of belief registers store beliefs that a corresponding symbol in the block has a certain value. Check processors determine output check-to-bit messages from input bit-to-check messages by message-update rules. Link processors connect the set of belief registers to the check processors. Each link processor has an associated message register. Messages and beliefs are passed between the set of belief registers and the check processors via the link processors for a predetermined number of iterations while updating the beliefs to decode the block of symbols based on the beliefs at termination.
