Bit Error Rate Performance of MIMO-NOMA with Majority Based TAS/MRC Scheme in Nakagami-m Fading Channels
(Institute of Electrical and Electronics Engineers Inc., 2022) Kumson, Princewill Kum; Russ, Rusul Al-Afah; Aldababsa, Mahmoud
The inability of conventional orthogonal multiple access (OMA) techniques to guarantee a low latency rate, high spectral efficiency, massive device connectivity, and a better quality of service (QoS) led to the introduction of the non-orthogonal multiple access (NOMA) technique. Multiple-input multiple-output (MIMO) technologies can increase the capacity and decrease the error rate of wireless systems. Due to the advantages mentioned earlier, integrating NOMA and MIMO is indispensable in future wireless communication systems. In this context, this paper considers MIMO-NOMA networks, in which all nodes are equipped with multiple antennas. In the considered network, the majority-based transmit antenna selection and maximal ratio combining schemes are employed at the base station and users, respectively. Then, the bit error rate performance is investigated over Nakagami-m fading channels by Monte Carlo simulations. © 2022 IEEE.
