AB  - In this paper, we propose an uplink IM-NOMA technique in which IM is applied to the existing NOMA, in order to support a military communication service that is robust to the jamming signal of the enemy in the military communication environment. We consider the channel estimation error for realistic military communication environment. We compare IM-NOMA with the conventional NOMA when there are PBJ and BJ. Through computer simulations, it can be confirmed that the IM-NOMA performs better than the NOMA system in both PBJ and BJ environments.
