Abstract
A hard decision memory interacts with a multi-layered low-density parity-check decoder by sending multiple L values and E values to a multi-layered low-density parity-check decoder (LDPC), and the L value E value hard decision memory (LE hard decision memory) receives one or more hard decisions. The LE hard decision memory comprises a global mapping element to interleave L values from a first and second circulant and store the interleaved values in a first memory element. A low-density parity-check decoder then processes the circulants from the first memory element and stores output in a second memory element. The LE hard decision memory does not include any mux-demux elements. The use of the LE hard decision memory results improved multi-level LDPC decoding of an LDPC encoded message.
