摘要：

Ambient backscatter communication (AmBc) is a modern communication technique that permits smart devices to transfer data with the aid of ambient radio frequency (RF) radiation. This letter investigates the issue of eavesdropper (ED) attacks on multi-tag AmBc systems. In particular, we explore a realistic scenario in which both the reader and the ED are in motion and analyze the influence of their motion on the AmBc system's secrecy performance when channel estimation is imperfect. Specifically, an analytical expression of secrecy outage probability (SOP) and an asymptotic SOP is derived. Also, the simulation results are shown to confirm the analytical expressions.
