Data-Oriented Performance of Energy Harvesting-Based Noncoherent Communications

Abstract

The data-oriented communications approach was initially introduced to develop novel transmission strategies for individual data sessions by accounting for instantaneous channel conditions under latency constraints. However, existing studies are limited to scenarios where channel state information (CSI) is either fully or partially available at the receiver, which may be impractical for short-packet transmissions. In this context, the present work focuses on analyzing the delay-outage rate (DOR), a data-oriented performance metric, under the noncoherent communications paradigm, where accurate CSI is not required. To this end, we first derive and calculate the DOR metric, which is then used to define transmission as well as receiver design requirements based on data and bandwidth parameters. Beyond emphasizing the significance of the new data-oriented DOR metric, the results provide valuable insights for designing and facilitating delay-sensitive and highly reliable noncoherent data transmission in future networks.
