Abstract :
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.
