Low Complexity FEC Systems for Satellite Communication
Ashwani Singh, Henry Chandran
In order to address low power, low processing delay requirement of emerging satellite communication systems, there is a need for low complexity small block length forward error correction (FEC) codes. Furthermore the new trends towards the convergence of wireless and satellite terminals would also mean co-existence of support for very short and the long blocks of data in the same device. In this context a novel next generation high performance 4K low density parity check (LDPC) code is introduced in the paper. The error performance results for the proposed code are presented showing significant improvement of performance/complexity metrics over existing FEC systems.
