  • Method and apparatus for implementing a low density parity check code in a wireless system
    Publication number: 20050166131
    Abstract: A low density parity check (LDPC) code is used within a wireless apparatus to perform forward error correction (FEC) coding. In at least embodiment of the invention, a (2000, 1600) bit-length LDPC code is used.

  • Method and apparatus for varying lengths of low density party check codewords
    Publication number: 20050154958
    Abstract: A method and apparatus for encoding/decoding information using low density parity check (LDPC) codewords of varying lengths. In one implementation, an encoder/decoder uses a parity check matrix having a size that corresponds to a length of information for each codeword. In one example, the size of the parity check matrix may be retrieved from multiple stored matrices having different sizes. In other examples, a mother code matrix may be dynamically adjusted by puncturing parity bits and/or deleting information bits. Other inventive embodiments and adaptations are also disclosed.
