Two-Way Source-Channel Coding

We propose an adaptive lossy joint source-channel coding (JSCC) scheme for sending correlated sources over two-terminal discrete-memoryless two-way channels (DM-TWCs). The main idea is to couple the independent operations of terminals via mechanism, which can mitigate cross-interference resulting from simultaneous channel transmissions and concurrently exploit sources' correlation reduce end-to-end reconstruction distortions. Our JSCC not only subsumes existing methods communication but also improves their performance. Furthermore, we derive outer bounds our transmission problem establish complete theorems in some special settings. In these cases, a non-adaptive separate (SSCC) achieves optimal performance, thus simplifying design system.
