  • Systems and methods for decoding cascade LDPC codes
    Patent number: 9537508
    Abstract: Systems and methods are provided for decoding a codeword of a low density parity check (LDPC) code. The systems and methods may include receiving a vector corresponding to the codeword encoded with a parity check matrix, and processing a first portion of the received vector with a first portion of the parity check matrix to obtain a decoding estimate of a first portion of the codeword. The systems and methods may further include processing the decoding estimate of the first portion of the codeword with a second portion of the parity check matrix to obtain an intermediate vector, and processing a second portion of the received vector with a third portion of the parity check matrix and the intermediate vector to obtain a decoding estimate of a second portion of the codeword.

  • Systems and methods for bit flipping decoding with reliability inputs
    Patent number: 9385753
    Abstract: Systems and methods are provided for decoding data. A decoder receives a variable node value and reliability data for a variable node, and check node values for check nodes associated with the variable node. Circuitry generates an updated variable node value, based on the received reliability data and the received check node values. The circuitry also generates, for at least one check node, an updated check node value based on the updated variable node value.

  • Systems and methods for decoding using partial reliability information
    Patent number: 9379738
    Abstract: Systems and methods are provided for decoding data. A decoder receives a plurality of variable node values for a plurality of variable nodes and processed reliability data for at least a subset of the plurality of variable nodes. Circuitry updates the variable node values based on the variable node values and the processed reliability data. The processed reliability data represents a version of the reliability data for at least the subset of the plurality of variable nodes.

  • Systems and methods for decoding with late reliability information
    Patent number: 9369152
    Abstract: Systems and methods are provided for decoding data. A variable node value for a variable node is received at a first time, and reliability data for the variable node is received at a second time. The variable node is decoded using a first decoding scheme after the first time and before the second time, and the variable node is decoded using a second decoding scheme different from the first decoding scheme after the second time.
