This study introduces an IRS-assisted design aimed at overcoming the outage floor challenge commonly seen in multi-user full-duplex (FD) cooperative systems, particularly in the presence of co-channel interference (CCI). It features two antenna modes named as dynamic antenna structure (DAS) and static antenna structure (SAS) applied to N FD relays and P IRS devices, each equipped with Q reflecting elements. A combined approach for selecting antenna modes, relays, and IRS nodes is employed to boost overall network performance. The analysis also considers how CCI affects the proposed schemes. In low to moderate power regions, the DAS and SAS methods achieve diversity gains of PQ+N and PQ+2N, respectively, highlighting the advantages of incorporating IRS nodes in a parallel structure. The research provides mathematical formulas for calculating outage probability, with simulation results confirming that the proposed scheme outperforms traditional FD cooperative systems. Notably, it successfully addresses the outage floor and capacity ceiling limitations. Additionally, the paper explores system performance with energy harvesting, demonstrating that increasing the time allocated for energy harvesting allows more energy to be gathered from primary transmitters, which can then be stored in rechargeable batteries.
