Low complexity FEC Systems for Satellite Communication

Abstract

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.

Implication of LDPC Technique in Non-ideal Multiuser Communication System

“…Low-density parity check codes (LDPC) have replaced turbocodes in various numbers of applications including DVB-S2 standard for satellite transmission of digital television [5]. Considering that they can be modeled as block codes, they can be implemented using more efficient and fast encoding/decoding algorithms being suitable for iterative decoding process.…”
