Conclusion :The downlink IM-NOMA system is analyzed by considering EE parameter.
Simulation results show that IM-NOMA provides a higher energy efficiency than OMA.
For a given M and L, the per user energy efficiency increases with the increase in the number of active subcarriers.
when K= L/2, energy efficiency attains it¡¯s maximum point.
As long as P is smaller than or equal to a certain threshold, the graph indicates the same energy efficiency value.
IMNOMA offers higher performance in terms of energy efficiency compared to OMA.
