Abstract
Teknologi 5G yang sedang dikembangkan akan menggunakan antena berbasis MIMO untuk memaksimalkan throughput pada pengirim. Antena MIMO mengimplementasikan metode Hybrid Beamforming yang merupakan gabungan antara sistem analog beamforming dengan digital beamforming yang bertujuan membuat sistem dengan kompleksitas yang rendah serta mencapai hasil yang hampir sama dengan menggunakan sistem full-digital beamforming. Pada tugas akhir ini, akan dilakukan perbandingan kinerja sistem point-to-point MIMO pada kanal independent Rayleigh fading dan kanal uniformly random Line-of-Sight (URLoS) menggunakan Hybrid Beamforming. Grafik spectral efficiency terhadap SNR pada dua kanal yang berbeda didapatkan melalui simulasi pada MATLAB sehingga dapat dilakukan analisis pengaruh kanal independent Rayleigh fading dan URLoS pada sistem.
Dari hasil simulasi, dapat diketahui bahwa sistem point-to-point large-scale array MIMO pada kanal URLoS memiliki kinerja spectral efficiency yang lebih baik dibandingkan dengan kanal IRF. Terdapat peningkatan kinerja spectral efficiency sebesar 45% pada kanal URLoS dibandingkan dengan sistem yang berjalan pada kanal IRF. Perbedaan kinerja tersebut disebabkan karena pada kanal IRF tidak terjadi korelasi kanal, sedangkan pada kanal URLoS, antena yang berdekatan akan mengalami korelasi kanal sehingga dapat menyebabkan interferensi sinyal.
====================================================================================================================
The 5G technology that is being developed will use MIMO-based antennas to maximize the throughput of the sender. The MIMO antenna will implement the Hybrid Beamforming method which is a combination of analog beamforming and digital beamforming systems that aim to create systems with low complexity and achieve almost the same results using a full-digital beamforming system. In this final project, we will compare the performance of point-to-point large-scale array MIMO systems on independent Rayleigh fading channels and uniformly random channels Line-of-Sight (URLoS) using Hybrid Beamforming. Spectral efficiency versus SNR graphs on two different channels are obtained through simulations on MATLAB so that analysis of independent Rayleigh fading and URLoS channels effects on the systems can be analyzed.
From the simulation results, it can be seen that the point-to-point large-scale array MIMO system on the URLoS channel has better spectral efficiency performance compared to the IRF channel. There is a 45% increase in spectral efficiency performance on URLoS channels compared to systems running on IRF channels. The difference in performance between those system due to the fact that there is no channel correlation in the IRF channel, while in the URLoS channel, adjacent antennas will experience channel correlation so that it can cause signal interference.
