“…Further, from the executed outcomes, the adopted scheme was found to have attained improved sum rates over the compared models. In 2019, Wu (2019) has developed a novel code-aided MIMO-NOMA approach for downlink transmissions. In this work, a simple grouping scheme was exploited, which have isolated all UTs in a cell into numerous clusters, in which the count was minimal or equivalent to BS antennas.…”

Purpose Non-orthogonal multiple access (NOMA) is a much hopeful scheme, which is deployed to enhance the spectral efficiency (SE) significantly, and it also enhances the massive access that has attained substantial concern from industrial and academic domains. However, the deployment of superposition coding (SC) at the receiver side resulted in interference. For reducing this interference, “multi-antenna NOMA” seems to be an emerging solution. Particularly, by using the channel state information at the transmitter, spatial beam forming could be deployed that eliminates the interference in an effective manner. Design/methodology/approach This survey analyzes the literature review and diverse techniques regarding the NOMA-based spatial modulation (SM) environment. It reviews a bunch of research papers and states a significant analysis. Initially, the analysis depicts various transmit antenna selection techniques that are contributed in different papers. This survey offers a comprehensive study regarding the chronological review and performance achievements in each contribution. The analytical review also concerns on the amplitude phase modulation (APM) selection schemes adopted in several contributions. Moreover, the objective functions adopted in the reviewed works are also analyzed. Finally, the survey extends with various research issues and its gaps that can be useful for the researchers to promote improved future works on NOMA-based SM. Findings This paper contributes to a review related to NOMA-based SM systems. Various techniques and performance measures adopted in each paper are analyzed and described in this survey. More particularly, the selection of transmission antenna and APM are also examined in this review work. Moreover, the defined objective function of each paper is also observed and made a chronological review as well. Finally, the research challenges along with the gaps on NOMA-based SM systems are also elaborated. Originality/value This paper presents a brief analysis of NOMA-based SM systems. To the best of the authors’ knowledge, this is the first work that uses NOMA-based SM systems to enhance SE.

“…Toplam verici gücü ve UK için veri oranı kısıtı altında, düşük karmaşıklıklı en iyiye yakın bir çözüm önerilmiştir. (Wu, 2019)'da yazarlar, çoklu erişimde güç düzleminde, girişimi ortadan kaldırmak amacıyla geleneksel aşağı yönlü NOMA sisteminde kullanılan SIC çözümünden ziyade kod yardımlı çok kullanıcılı aşağı yönlü iletimde MIMO-NOMA yapısı önermişlerdir. Kullanıcı düğümlerinin tek bir hücre içinde birden fazla küme ile gruplandığı ve her bir küme için ortogonal kodların üretildiği çözümde, kümeler arası girişimin giderilmesi başarımından bahsedilmektedir.…”

Bu çalışmada, röle yardımlı aşağı yönlü dikgen olmayan çoklu erişim (NOMA) sistemlerinin bilişsel radyo ağlardaki ergodik kapasite analizi incelenmektedir. Önerilen sistem modelindeki matematiksel çıkarımlar, ikincil ağdaki yakın ve uzak kullanıcılar için tam ve yaklaşık ergodik kapasite kapalı form denklemlerinin üstel dağılımlı kanal göz önüne alınarak türetilmesiyle elde edilmektedir. Hem rölede, hem de yakın ve uzak kullanıcılarda ardışık girişim iptali gerçekleşmesi durumunda, toplam ergodik kapasite performansı düğümler arası mesafe, güç paylaşım katsayısı, iletim gücü ve yol kaybı üssü parametreleri dikkate alınarak, 10 6 tekrarlı Monte Carlo benzetimleriyle analiz edilmektedir. Elde edilen nümerik sonuçlar, yakın kullanıcıya atanan güç tahsisinin artması ile ergodik toplam kapasitenin arttığını göstermektedir. Birincil ağ vericisinin röleden uzaklaşmasının sistem performansını iyileştirdiği de gözlenmiştir. Yakın kullanıcı için tam olarak hesaplanan ergodik toplam kapasite başarımının, yaklaşık olarak hesaplanan ergodik toplam kapasite performansı ile örtüşmesi, ancak yüksek işaret gürültü oranı (SNR) bölgesinde mümkün olmaktadır. Bu durum, ikincil ağ olarak kurgulanan aşağı yönlü NOMA sisteminin, ortak kanal girişimi olarak etki gösteren birincil ağ ile aynı frekans bandını kullanmasının etkisi olarak değerlendirilmiştir.
