Active IRS-aided NOMA with full-duplex energy harvesting wire-tapper: Performance evaluation

Year: 2025

Type: article

Abstract: Wireless communication is quickly degraded due to obstacles in signal propagation. These obstacles can be remedied with intelligent reflecting surface (IRS), which purposely changes propagation conditions. However, security is a big concern in wireless communication, where active eavesdroppers are capable of energy harvesting (EH) and interfere with authorized users. This work analyzes a system model in which a full-duplex (FD) source scavenges energy from the power station and broadcasts a non-orthogonal multiple access (NOMA) signal to a close user and a distant user with the aid of active IRS (mainly reducing double loss due to double reflection) subject to a FD wire-tapper with ability of EH and interfering licensed users. By security analysis, the proposed system (active IRS-aided NOMA with FD EH wire-tapper) is demonstrated better than its counterpart (active IRS-aided orthogonal multiple access with FD EH wire-tapper).
