Özet
Cooperative nonorthogonal multiple access (NOMA) system is an effective solution for the fifth generation (5G) wireless mobile communications systems. In this work, the achievable rate analysis of a NOMA communication network with decode-and-forward (DF) relaying under kappa-mu shadowed fading conditions is investigated. First, we develop an analytical framework for cumulative distribution function (CDF) of the considered system model. Then, the average achievable rate expressions for two different information bits namely s(1) and s(2) are derived based on the derived CDF for NOMA with DF relaying over kappa-mu shadowed fading channels. Furthermore, we also propose simplified average achievable rate expressions for the special cases of kappa-mu shadowed fading channels in order to facilitate the evaluation of the derived expressions. Some numerical examples on the achievable rate of the considered system are shown for different scenarios. Moreover, our derived analytical average achievable rate expressions are confirmed by the simulations results.
