description | Abstract Intelligent reflecting surface (IRS) is regarded as a promising emerging technology, which has shown enormous potentials for performance enhancement. This paper investigates the multiple IRS‐aided dual‐hop DF relaying system for both single‐user and multi‐user scenarios over Nakagami‐m fading. Based on a scenario with non‐orthogonal multiple access users, tight upper bounds for the ergodic capacity in perfect channel state information(pCSI) scenario are first derived, and then approximate expressions are obtained in imperfect CSI (ipCSI) mode. Moreover, the performance of multiple IRS‐aided DF relaying system are compared with multi‐IRSs‐only system and DF relaying‐only system. Finally, all the analytical results are verified using Monte Carlo simulations. |
