LDPC-codes

LDPC-codes is a collection of programs and modules intended to support research and education concerning Low Density Parity Check (LDPC) codes. The decoding algorithm for LDPC codes is related to that used for Turbo codes, and to probabilistic inference methods used in other fields. Variations on LDPC and Turbo codes are currently the best practical codes known, in terms of their ability to transmit data at rates approaching channel capacity with very low error probability.

    Release Notes: This release includes random functions from glibc to standardize them. It adds an -f option to encode and decode that forces flushing after writing each block. It adds a -z option for pchk-to-alist to suppress output of 0 row and column indexes that pad up to the maximum number used. It documents the previously undocumented -t options for pchk-to-alist and alist-to-pchk. Bugfixes and code cleanups. The advertising clause has been removed from the license.
