Coverage Probability Analysis Under Clustered Ambient Backscatter Nodes

In this letter, we consider a new large-scale communication scheme where randomly distributed backscatter nodes are involved as secondary users to primary transmitter and primary receiver pairs. The secondary communication between a backscatter transmitter and a backscatter receiver introduces additional double fading channels and has a two-side effect to the primary communications. We derive the signal-to-interference-plus-noise ratio and signal-to-interference ratio based coverage probabilities for two network configuration scenarios.
