Abstract

The present invention provides a low density parity check (LDPC) code system and method of using such a system. A transmitted LDPC code block size may be chosen such that the minimum transmitted block size is minimized. Further the system provides for intermediate LDPC code block size support. Finally a common decoder architecture may be used to decode different LDPC code rates and block sizes.
