Optimal age over erasure channels
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 … 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 …

WebFeb 1, 2024 · A novel framework of optimal performance for NCSs over power constrained erasure channels with feedback and packet-dropouts is established. (2) Exact expressions of the optimal performance are derived by using the frequency domain analysis methods including the allpass factorizations, Youla parameterization of all stabilizing controllers … WebAug 18, 2024 · Abstract: A status updating system is considered in which data from multiple sources are sampled by an energy harvesting sensor and transmitted to a remote destination through an erasure channel. The goal is to deliver status updates of all sources in a timely manner, such that the cumulative long-term average age-of-information (AoI) is …
