Short-Packet Backscatter Assisted Wireless-Powered Relaying With NOMA: Mode Selection With Performance Estimation

Backscatter-assisted wireless-powered relaying has emerged as a promising approach to extend the transmission range of energy-constrained devices, e.g., sensors, with improved energy efficiency. Mode selection adapting to the dynamic channel conditions has a great impact on the performance of this hybrid relaying paradigm. However, designing an effective mode selection is challenging as the instan...
