Secrecy Analysis of CSI Ratio-Based Transmitter Selection with Unreliable Backhaul
Burhan Wafai, Ankit Dubey, Chinmoy Kundu
This paper explores the secrecy performance of a multi-transmitter system with unreliable backhaul links. To improve secrecy, we propose a novel transmitter selection (TS) scheme t…
