To increase the system capacity of IRS-assisted OAM communication systems, we propose the IMI cancellation method for IRS-assisted OAM multiplexing and the L2-ball projection approaches to optimize the transmit power allocation for OAM modes. The simulation of the IRS-assisted OAM communication shows that the IMI cancellation method can achieve increasing the maximum system capacity. It also shows that the L2-ball projection method can achieve increasing the maximum system capacity as compared to the L1-ball projection method, but it is limited to when the IRS is placed near the middle.
