On different ldfc-based joint source-channel optimised decoding schemes
Charly Poulliat, David Declercq, L. Fijalkow, Catherine Lamy–Bergot · 2005
In this paper, we compare different joint channel decoding (JSCD) schemes involving LDPC codes: (i) JSCD optimised, (ii) non-JSCD compatible optimised, and finally (iii) an optimal tandem system assuming perfect source compression. Some optimisation and simulation results are provided for different rates and codeword lengths.
