Abstract
5G overcame the severe shortage of cellular spectrum used by its predecessors by using millimeter-wave (mmWave) packets that provide broadband to 5G wireless networks. The problem of Inter User Interference (IUI) is also one of the most important and dangerous problems facing telecommunication networks. IUI is exacerbated, especially in the areas near the Tower as the narrow coverage area compared to the areas farthest from the Tower. As a result of this effect, our paper proposes a new model by taking a matrix of antennas at different heights and coordinating mmWave beams. Coordinated Multi-Point (CoMP) is the essential solution in 5G to improve throughput and coverage performance. As a result, millimeter wave technology was used in the proposed CoMP system. The new proposed system works to study the effect of the height of the antenna matrix on reducing IUI by calculating the peak capacity value on the user with different distances. In addition to the impact of the azimuth angle of arrival AoA (∅) on capacity when implementing each scenario. Simulation results show that the proposed system scheme with different heights of the antenna matrix can get a large capacity than a traditional system. Choosing the best antenna matrix height reduces interference and improves capacity. The highest improvement obtained is 53%.
