Achievability proof of some multiuser channel coding theorems using backward decoding
Chaolv Zeng, F. Kuhlmann, Andres Buzo · IEEE Transactions on Information Theory · 1989
New and simpler achievability proofs that are based on the backward decoding technique are presented for the well-known coding theorems for the multiple-access channel (MAC) with perfect feedback and the degraded relay channel. A class of MACs with different generalized feedback signals is also considered, and achievable-rate regions that are larger than those previously presented in the literature are established.>
