With the increasing number of users using wireless applications, it is necessary to make the various user desired services such as internet, video conference, and many more applications to be available to users at any time they need with an acceptable scenario of waiting states. Multiple access techniques make this happen by distributing the channels to all the users accessing the network for which proper utilization of resources plays a key role. The newest category under this concept is Non-Orthogonal Multiple Access (NOMA) technique. The key idea of the proposed work is to efficiently utilize the resources allocated to the system in the whole process of communication. This is done through optimization of resources. The power optimization concept is given importance in this framework. The scenario of making the best use of power is framed as non-convex. The enhancement in the other objective function such as maximization of the probability of detecting the correct information at the receiver is also considered which is viewed as convex resource. The results are obtained by performing simulation using MATLAB and these are evident that the performance of NOMA is efficient and conveys that NOMA is having better performance than the conventional orthogonal scheme.
