Performance Evaluatıon of Beamformıng in 5G OFDM Systems and Advantages over 4G

Abstract

This paper investigates the performance of 5G networks. It focuses on the
implementation and advantages of Orthogonal Frequency Division Multiplexing
(OFDM) and beamforming compared to 4G LTE systems. Through MATLAB
simulations, it examines critical performance metrics, including signal-to-noise
ratio (SNR), throughput, and latency, highlighting the benefits of 5G in enhancing
data transmission rates, reducing latency, and supporting higher user density.
Beamforming, a core component in 5G, enables directional signal transmission,
significantly improving signal quality and reducing interference, especially in
dense and urban environments. The results indicate that 5G, with its advanced
technologies, outperforms 4G by delivering improved connectivity, increased
network capacity, and low-latency communication, which are essential for
emerging applications like IoT, autonomous vehicles, and augmented reality.
Limitations related to frequency bands, simulation constraints, and scalability are
acknowledged, with recommendations for future research focused on diverse
testing conditions, higher frequency bands, and optimization techniques. This
study underscores the transformative potential of 5G technology in modern
wireless communications, setting the stage for future advancements as we transit
toward 6G.
