An achievable region for the discrete-memoryless multiple access channel (DM-MAC) with correlated sources and feedback is characterized, based ona modification of the Cover-El Gamal-Salehi approach for DM-MAC without correlated sources. Two different sufficient conditions for this region to be the optimal joint source-channel coding region are provided alongw ith an example scenario where each condition holds. The achievable region is subsequently generalized to the case of discrete-memoryless interference networks with feedback. The special case of Gaussian multiple with correlated sources and feedback is also investigated, with a modified Schalkwijk-Kailath coding scheme used to devise an achievableregion for the system.
