基于IRS的D2D隐蔽通信
D2D covert communication based on IRS
摘要
Abstract
A device to device(D2D)communication system using two intelligent reflecting surfaces(IRSs)is proposed to investigate D2D covert communication.Firstly,the signal to interference noise ra-tio(SINR)and the expectant of each signal are analyzed.Based on these,the solution form of the ergo-dic sum capacity of the system is obtained.Secondly,a binary hypothesis testing problem is proposed to obtain the solution form of the total detection error probability(DEP).Then,the average minimal DEP is calculated.In addition,the ergodic sum capacity and the average minimal DEP of the normal system are analyzed and compared with those of the IRS system.Simulation results show that the performances of the IRS system are better with higher ergodic sum capacity and lower average minimal DEP.关键词
