The capacity of the white Gaussian multiple access channel with feedback
Abstract
Gaarder and Wolf (1975) established that feedback can enhance the capacity region of the multiple access channel (MAC). A deterministic feedback code is given for the two-user Gaussian MAC which will allow reliable communication at all points within a region that is larger than any heretofore obtained. An outer bound is determined which is noted to coincide with the achievable region, thereby yielding the channel's exact capacity region.
