Oct 22, 2024 · We jointly optimize the rate threshold and the packet transmission time to maximize the average throughput of SU, while limiting interference to ...
We show how a secondary user (SU) can leverage the structure induced by block-based network coding on a primary user's (PU) channel to maximize the throughput.
This work presents Uniforming Random Ordered Policy (UROP) and shows UROP achieves near-optimal throughput under block fading assumption for generic channel ...
