Surat ini membentangkan teknik akses berbilang bukan ortogon (NOMA) untuk sistem berbilang input berbilang input (MIMO) dua sel yang mengeksploitasi penjajaran saluran gangguan antara sel dan saluran isyarat dalam kelompok dalam sel. Teknik yang dicadangkan mencari vektor penggabung untuk pengguna yang menyelaraskan saluran gangguan antara sel dan saluran isyarat secara serentak. Teknik ini menggunakan saluran gangguan dan isyarat sejajar untuk mendapatkan matriks prakoder untuk stesen pangkalan yang melaluinya setiap aliran data yang dimodulasi oleh NOMA boleh dihantar ke kluster yang dimaksudkan tanpa gangguan. Selain itu, kami memperoleh syarat yang mencukupi untuk menghantar dan menerima konfigurasi antena dalam sistem MIMO NOMA untuk menghapuskan gangguan antara sel dan gangguan antara kelompok secara serentak. Oleh kerana teknik yang dicadangkan secara berkesan menindas gangguan antara sel, ia mencapai tahap kebebasan yang lebih tinggi daripada teknik sedia ada yang bergantung pada pengelakan gangguan antara sel, dengan itu memperoleh prestasi kadar jumlah yang lebih baik di kawasan SNR yang tinggi. Tambahan pula, kami mempersembahkan teknik MIMO NOMA hibrid, yang menggabungkan teknik MIMO NOMA yang mengeksploitasi penjajaran saluran dengan teknik sedia ada yang meningkatkan kuasa isyarat yang diterima. Menggunakan faedah daripada teknik ini, teknik hibrid yang dicadangkan mencapai prestasi yang baik dalam semua wilayah SNR. Keputusan simulasi berjaya menunjukkan keberkesanan teknik yang dicadangkan pada prestasi kadar jumlah.

Abstract: This letter presents a non-orthogonal multiple access (NOMA) technique for a two-cell multiple-input multiple-output (MIMO) system that exploits the alignments of inter-cell interference channels and signal channels within a cluster in a cell. The proposed technique finds combiner vectors for users that align the inter-cell interference channels and the signal channels simultaneously. This technique utilizes the aligned interference and signal channels to obtain precoder matrices for base stations through which each data stream modulated by NOMA can be transmitted to the intended cluster without interference. In addition, we derive the sufficient condition for transmit and receive antenna configurations in the MIMO NOMA systems to eliminate inter-cell interference and inter-cluster interference simultaneously. Because the proposed technique effectively suppresses the inter-cell interference, it achieves a higher degree of freedom than the existing techniques relying on an avoidance of inter-cell interference, thereby obtaining a better sum rate performance in high SNR regions. Furthermore, we present the hybrid MIMO NOMA technique, which combines the MIMO NOMA technique exploiting channel alignment with the existing techniques boosting the received signal powers. Using the benefits from these techniques, the proposed hybrid technique achieves a good performance within all SNR regions. The simulation results successfully demonstrate the effectiveness of the proposed techniques on the sum rate performance.
