Abstract

5G teknolojisi ile mmDalga bandında kullanılacak kanal modellerinin analizleri sistem performansı açısından oldukça önemlidir. Bu çalışmada NYUSIM kanal modelleyici kullanılarak 28 GHz ve 73 GHz frekanslarının, verici alıcı anten sayısının ve LOS/NLOS parametrelerinin 5G kanal kapasitesine etkisi incelenmiştir. Analizler sonucunda; 28 GHz için 2x2’den 64x64’lük anten yapısına geçildiğinde kapasite artışı LOS için 29.78 kat iken NLOS için bu değerin 26.91 kat olduğu görülmüştür. 73 GHz için ise 2x2’den 64x64’e geçildiğinde kapasite artışı LOS için 36.88 kat iken NLOS için ise 29.00 kattır. 64x64 anten yapısı için 28 GHz ve LOS için kanal kapasitesi 73 GHz’den 8.81 kat daha fazla iken bu değer NLOS için 12.56 kat kadardır. 28 GHz 64x64 yapısı ve LOS durumu için kanal kapasitesi NLOS durumuna göre 215.69 kat daha fazla iken bu değer 73 GHz için 307.7 kattır.

Analysis of MIMO Channel Capacity at 28/73 GHz with NYUSIM Channel Simulator

Abstract

Analyzing the channel models in the mm-wave bandwidth is critical for 5G system performance. This study investigated the effects of 28 GHz and 73 GHz frequencies, the number of transmitting and receiving antennas, and LOS/NLOS parameters on 5G channel capacity using the NYUSIM channel simulator. As a result of the analysis, changing from a 2x2 to a 64x64 antenna structure for 28 GHz increased capacity by 29.78 times for LOS and 26.91 times for NLOS. When changing the MIMO configuration from 2x2 to 64x64 at 73 GHz, the channel capacity rises 36.88 times for LOS and 29.00 times for NLOS. With a 64x64 antenna structure, the channel capacity for 28 GHz and LOS is 8.81 times higher than for 73 GHz, and it is 12.56 times higher for NLOS. For the 28 GHz 64x64 structure and LOS condition, the channel capacity is 215.69 times higher than the NLOS condition, while this value is 307.7 times for 73 GHz.
