Design of Joint Source-Channel Coding Scheme Based on Spatially-Coupled DP-LDPC Codes

In this letter, we propose a novel joint source-channel code (JSCC) called spatially-coupled double-protograph-based low-density parity-check (SC-DP-LDPC) code. The SC-DP-LDPC code consists of a source spatially-coupled protograph-based low-density parity-check (SC-P-LDPC) code and a channel SC-P-LD...

Zusammenfassung:In this letter, we propose a novel joint source-channel code (JSCC) called spatially-coupled double-protograph-based low-density parity-check (SC-DP-LDPC) code. The SC-DP-LDPC code consists of a source spatially-coupled protograph-based low-density parity-check (SC-P-LDPC) code and a channel SC-P-LDPC code. Moreover, the two corresponding protomatrices are connected by a spatially-coupled source-check-channel-variable (SC-SCCV) linking protomatrix. Theoretical and simulation results show that the SC-DP-LDPC codes outperform JSCC systems based on state-of-the-art double protograph-based LDPC block codes or concatenated spatially-coupled LDPC codes.
