In this paper, an intelligent reflecting surface (IRS) assisted cooperative non-orthogonal multiple access and mobile edge computing (NOMA-MEC) system is proposed, where a base station sends signals to users through the virtue of IRS. When direct links between user are blocked, offloading tasks will be refracted near-end IRS forwarded remote user, equipped with MEC server working at full duplex...

Effect of multipath fading can decrease the performance of wireless communication systems. The multiinput multi-output (MIMO) technique, which uses multiple antennas, often used to overcome multipath fading. This technique is one of the diversity techniques. Some wireless devices have limitation about the size, cost, and hardware complexity, so there can not implement a multiple antenna. Then, ...
