摘要：

To overcome the double path loss in Intelligent Reflecting Surface (IRS) assisted communication system and further enhance the reliability and spectral efficiency, a Reflection Modulation (RM) system scheme based on grouping of active IRS reflecting elements is proposed. This scheme utilizes the number of active reflecting element groups to transmit additional information. Then the average pairwise error probability of both the symbols transmitted by base station and the number of active reflecting element groups under the maximum likelihood detection algorithm is derived based on the moment generating function, and an upper bound on the theoretical Bit Error Probability (BEP) as well as the achievable data rate of the system are obtained. Simulation results verify the accuracy of the theoretical derivation and demonstrate the superior error performance and spectral efficiency of the proposed scheme. © 2024 Science Press.
