Optimal age over erasure channels
WebMay 24, 2024 · In this paper, we examine a status updating system where updates generated by the source are sent to the monitor through an erasure channel. We assume each update consists of k symbols and the symbol erasure in each time slot follows an independent and identically distributed (i.i.d.) Bernoulli process. We assume rateless coding scheme is … WebJan 6, 2024 · Here, we define the concepts of achievable age and optimal achievable age. Definition 1. We call C=(fi,gi)i≥1 to be a coding scheme where (fi)i≥1 is the sequence of …
