New energy-efficient-user clustering and power allocation for NOMA in 5G millimeter-wave massive MIMO

In wireless communications, designing Data Rate (R) and Energy Efficient (EE) Beamspace-Multiple Inputs Multiple Outputs (BS-MIMO) for the millimetre wave communications are challenging research problems from the last decade. There are different solutions presented such as Fully-Digital (FD), BS-MIM...

There are different solutions presented such as Fully-Digital (FD), BS-MIMO, and BS-MIMO Non-Orthogonal Multiple-Accesses (BS-MIMO NOMA). To address these problems, a novel mm-Wave communication is proposed with a user clustering approach called BS MIMO C-NOMA.

In this thesis, a lens antenna was used in the experiment to assess the lens's effectiveness in maximizing the signal. The simulation outcomes demonstrate the R and EE in C-NOMA are much higher than in NOMA by a percentage of 4.2 % and 26 % respectively, It means R is increased 6 % with a maximum of 50 users in C-NOMA compared to NOMA, and an increase of 3.92 % with a maximum 100 users. Then, EE results with a maximum 50 users for FD, MIMO, NOMA and C-NOMA are 1.172, 7.249, 10.879 and 13.72, respectively. Therefore, EE effects against SNR with 32 users in C-NOMA is 10.11 the highest compared to FD, MIMO and NOMA with 1.23, 6.58 and 7.58, respectively. The EE results of maximum 100 users for FD, MIMO, NOMA and C-NOMA are 1.29, 4.08, 7.85 and 10.82, respectively. The results of EE in C-NOMA show an increase of 37 % compared to NOMA with a maximum of 100 users. Signal strength result is increased from -18 dBm to -11 dBm by using the lens. We believe the proposed C-NOMA method can achieve higher result of R and EE compared to NOMA. 2022-06 Thesis http://eprints.uthm.edu.my/8384/ http://eprints.uthm.edu.my/8384/1/24p%20AL%20FATLI%20HAITHAM.pdf text en public http://eprints.uthm.edu.my/8384/2/AL%20FATLI%20HAITHAM%20COPYRIGHT%20DECLARATION.pdf text en staffonly http://eprints.uthm.edu.my/8384/3/AL%20FATLI%20HAITHAM%20WATERMARK.pdf text en validuser phd doctoral Universiti Tun Hussein Onn Malaysia Fakulti Kejuruteraan Elektrik dan Elektronik
