Abstract
A LDPC decoder utilizes a new schedule that breaks a dependency between data of different layers of a parity check matrix, so that the forward scan in the next layer can begin to perform after a predetermined time has elapsed (i.e. a delay) since the backwards scan of the previous layer has begun, and before the backwards scan of the previous layer is completed. Accordingly, the computation at the next layer can begin as soon as possible.
