Abstract

This paper considers a compound multiple access channel (MAC), where two transmitters send two messages to two receivers respectively and each receiver decodes both the source messages. In particular, transmitter cooperations by utilizing in-band full-duplex (FD) amplify-and-forward (AF) scheme are deployed to enhance the system performance. Based on the proposed scheme, the equivalent channel model is analyzed, as well as the statistics of the accumulated residual self-interference and noise (ARIN). With the joint decoding scheme, the corresponding achievable rate region is derived by a two-step iterative algorithm. Simulation results reveal that the proposed scheme can significantly improve the achievable rate under several typical scenarios.
