Application of Dual IRS-assisted MISO System in Communication Security Risk Management
In the information age,the information travels faster.In order to solve the security risks faced by wireless communi-cation,it is necessary to explore more effective communication security risk management methods.The intelligent reflector sur-face(IRS)is studied,and a multi-input single-output(MISO)secure communication system based on dual IRS-assissted is de-signed.The algorithm of alternating particle swarm optimization(PSO)is applied to optimize the problem of maximization of system security rate.When the IRS reflection unit is 16,the system security rate increases almost linearly when the transmit-ting power of the base station reaches 35 dpm,and reaches 10.6 bps/Hz at 60 dpm.The experimental results show that the MISO security communication system with dual IRS-assisted has a good performance of system security rate and can meet the needs of practical applications.
