Proactive Monitoring via Passive Reflection Using Intelligent Reflecting Surface
IEEE Communications Letters, 2020To monitor wireless suspicious transmissions, we propose an intelligent reflecting surface enabled legitimate monitoring system. In the system, the monitor employs the passive reflection for constructive or destructive signal forwarding. For constructive passive reflection, we maximize the average monitoring rate by approximating the cumulative ...
