  • DVB-S2 LDPC decoder using overlapped decoding scheme
    Patent number: 9882584
    Abstract: Provided is a low density parity check decoder, which includes a bit node calculating unit configured to calculate a bit node, a check node calculating unit configured to calculate a check node, a control unit configured to control calculation of the bit node and the check node, and a storage unit configured to store calculation values of the bit node or the check node, wherein the control unit calculates the bit node or the check node so that the node calculations are overlapped, by using an address offset value of the storage unit, thereby reducing a decoding time.
    Type: Grant
