Recently researchers are paying more attention to do a work in Non-orthogonal multiple access (NOMA) technique due to its cost effectiveness to enrich the spectral efficiency. This helps in increasing the capacity of advanced wireless systems without expanding the bandwidth. This paper investigate various power allocation schemes which are used in Non Orthogonal multiple access wireless communication and proposed modified power optimization scheme under maximum fairness constraints between users throughput. We also discuss spectral efficiency and Energy efficiency Tradeoff for both NOMA and OMA system and simulation results shows that NOMA has improved results compare to OMA.
