Abstract

In the last decade, Multiple-Input Multiple-Output (MIMO) algorithms have been developed for mobile communication networks in order to increase spectrum efficiency and reduce transmitted power, which are also two of the main Key Performance Indicators of Fifth Generation New Radio (5G NR). Therefore, various MIMO algorithms are being researched for their adaptability to 5G NR specifications. The objective of this study is to examine the array gains achieved with the deployment of multiple transmit antennas and multiple receive antennas in 5G NR Physical Downlink Shared Channel (PDSCH). The study first examines the array gains of Single-Input Multiple-Output (SIMO) and Multiple-Input Single-Output (MISO), then combines the transmitter and the receiver diversities in a MIMO system for 5G PDSCH. The array gains are achieved through precoding and combining vectors obtained by Singular Value Decomposition (SVD) of the channel coefficients matrix. The results show that theoretical array gains can be achieved in end-to-end 5G NR downlink channels.

Özet

Son on yılda, mobil iletişim ağlarında spektrum verimliliğini artırmak ve kullanılan iletim gücünü azaltmak için Çoklu Giriş Çoklu Çıkış (ÇGÇÇ) algoritmaları geliştirilmiştir. Spektrum verimliliğini artırmak ve kullanılan iletim gücünü azaltmak Beşinci Nesil Yeni Radyonun (5G YR) da Temel Performans Göstergelerinden olduğundan MIMO algoritmalarının 5G YR spesifikasyonlarına uygunluğu araştırılmaktadır. Bu çalışmanın amacı, 5G YR Fiziksel Aşağı Yönlü Bağlantı Paylaşımlı Kanalında (FAYBPK) çoklu verici antenler ve çoklu alıcı antenler kullanılarak elde edilen dizin kazançlarını incelemektir. Çalışma, Tekli Giriş Çoklu Çıkış (TGÇÇ) ve Çoklu Giriş Tekli Çıkış (ÇGTÇ) dizin kazanımlarını inceler, ardından 5G YR FAYBPK ÇGÇÇ sisteminde verici ve alıcı çeşitliliklerini birleştirir. Dizin kazanımları, Tekil Değer Ayrıştırma (TDA) ile elde edilen ön kodlama ve birleştirme vektörlerini kullanılarak elde edilir. Çalışma sonuçlara göre teorik dizi kazanımları baştan-uca 5G YR aşağı bağlantı kanallarında elde edilebilmektedir.
