WebPDF - Given a source that produces a letter every T s seconds and an erasure channel that can be used every T c seconds, we ask what is the coding strategy that minimizes the time-average "age of information" that an observer of the channel output incurs. We will see that one has to distinguish the cases when the source and channel-input alphabets have equal … Optimal Age over Erasure Channels Elie Najm, Emre Telatar, and Rajai Nasser Abstract Previous works on age of information and erasure channels have dealt with speciﬁc models and computed the average age or average peak age for certain settings.
