Abstract

In this paper, we derive a new achievable rate region for the two-way channel (TWC) with common output. The achievable rate region is based on two auxiliary directed graphs that represent the information that is used by each of the terminals. For any choice of the two auxiliary graphs, the achievable rate region is expressed with single-letter expressions. A degenerate choice of the auxiliary graphs, each with a single node, reduces the new achievable rate region to the Shannon's inner bound. We also show that the achievable rate region outperforms the Shannon's inner bound. This is shown with an explicit calculation of the achieved rate for the binary multiplying channel (BMC), using the inputs distribution from the Schalkwijk 82 scheme.
