Abstract
Look-ahead LDPC decoder. In an exemplary embodiment, a method includes generating a message (QA) to a first check node, the QA message is generated from a result (RA) from the first check node, and generating a message (QB) to a second check node, the QB message is generated from the result (RA) and is transmitted to avoid decoder stall. The method also includes receiving a result (R'A) from the first check node, computing a difference (R″A) between the result (R′A) and the result (RA), and receiving a result (R′B) from the second check node. The method also includes computing a bit value P(B) using the difference (R″A) and the result (R′B).
