LDPC large block FEC codec

We developed a large block LDPC (low-density parity-check) codec. Our codec is the only Open-Source, patent free, large block FEC (Forward Error Correction) codec for the Packet Erasure Channel (e.g. Internet) available today. It is both integrated in our MCLv3 library and distributed independently in order to be used by third parties in their own applications or libraries. This software, which is unique in the world, has experienced a lot of interest in both academic and industrial environments. In particular, this work has been largely supported by STmicroelectronics and the LDPC FEC codes are currently being considered for possible standardization in the IETF and DVB-H/SH organizations.
