Abstract: Although Shannon’s work showed that feedback does not increase capacity in point-to-point communication,s it is known to be quite useful in multi-terminal systems. Notably, feedback has long played a major role in the development of wireless networks, from its earliest and simplest uses in protocols such as Aloha, to its more sophisticated uses in advanced multiple-antenna systems. Recent years have seen a considerable research effort in this area, both on the practical uses of feedback and on the fundamental, and sometimes surprising, properties that it can impart to networks. This talk will review some of the latter developments, notably as they relate to the capacities of interference and MIMO broadcast channels.
