Özet

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.
