Abstract
Non‐orthogonal multiple access (NOMA) is a key technology beyond 5G/6G wireless and mobile communication systems. Simply because of the high efficiency of resource utilization, the system can meet the ever‐increasing requirements of higher data rates and ultra‐reliability. Keeping that in mind, we seek in this paper to derive simple closed‐form expressions to compute the maximum achievable user rate and formulate the probability density function of the SNR and SINR in the system. In addition to that, we determine the outage probability of the system in a generalized and explicit form. All of that is in terms of the user's deterministic propagation channel parameters, such as power allocation factor, noise level, position, and pathloss coefficient. Simulation results validate the accuracy of the obtained formulae.
