Opportunistic Ambient Backscatter Communication in RF-Powered Cognitive Radio Networks
Opportunistic Ambient Backscatter Communication in RF-Powered Cognitive Radio Networks
In the present contribution, we propose a novel opportunistic ambient backscatter communication (ABC) framework for radio frequency (RF)-powered cognitive radio (CR) networks. This framework considers opportunistic spectrum sensing (SS) integrated with ABC and harvest-then-transmit (HTT) operation strategies. Novel analytic expressions are derived for the average throughput, the average energy consumption …
