Robust LDPC decoding using irregular decoders
Raman Yazdani, Masoud Ardakani · IEEE Communications Letters · 2008
It has been observed that irregular decoders for low density parity-check (LDPC) codes can be more robust to channel estimation errors compared to conventional decoders. In this work, by presenting a robustness measure, we propose a method for the joint optimization of irregular LDPC code-decoder pairs to have the widest convergence region when channel estimation errors exist.
