Abstract

In today's world, billions of devices are being connected to the internet primarily through wireless means, making this connectivity increasingly important. Managing these connections becomes complex, especially for moving devices such as drones and high-speed trains, which require seamless and reliable connectivity even at high speeds. Maintaining a stable connection in fast-moving environments is challenging but essential for the operation of these technologies. Traditional communication systems like OFDM face significant challenges in high mobility environments, struggling to cope with the rapid changes and dynamic conditions that high-speed movements introduce. To address this, OTFS is proposed as a solution. This novel modulation framework operates in the delay-Doppler domain, allowing a two-dimensional representation of the channel's behavior over time and frequency. In this paper, various simulations of OTFS and OFDM were conducted under the same parameters and conditions. The results strongly advocate for the implementation of OTFS as a modulation scheme in future wireless communication systems, demonstrating superior performance and reliability compared to traditional OFDM, and highlight OTFS's potential to satisfy the growing need for high-speed, dependable communication in the rapidly advancing wireless technology landscape.
