Abstract: Recently, researchers are having more focus to work in the field of Non-Orthogonal Multiple Access (NOMA) network to address the emerging challenges of advanced wireless communication due to its cost effectiveness to enhance spectral efficiency. This helps in increasing the capacity of advanced wireless systems without expanding the bandwidth. This paper investigates various power allocation schemes which are used in power domain non-orthogonal multiple access wireless communication and suggests improved power allocation technique under optimum fairness constraints between users' capacity. We also discuss spectral efficiency and energy efficiency trade-off for proposed NOMA and conventional orthogonal systems and simulation results show that the proposed scheme for NOMA has improved results compared to different power allocation techniques and Orthogonal Multiple Access (OMA) system.
