This research examines how Nextgen wireless systems can benefit from Orthogonal Time Frequency Space (OTFS) modulation in different high-mobility channel situations. We test the BER performance of OTFS and OFDM with varying lengths of symbol under varied transmit power (TX power) conditions utilizing simulations employing Doubly-Selective, Extended Vehicular A (EVA), Unmanned Aerial Vehicle (UAV), and Extended Typical Urban (ETU) channel models. Compared to OFDM, OTFS reliably reduces the impact of multipath propagation and Doppler spread more effectively. Importantly, to maximize BER performance in UAV channel simulations, the OTFS symbol length had to be carefully selected; increasing the symbol length without thinking about it led to decreasing results. It was shown that OTFS is connected to a few resources in the ETU channel due to its minimal demand on TX Power. Based on these results, OTFS seems to be a good modulation technique for demanding mobile communication applications, particularly for UAV communications where picking the right parameters is key. Methods for adaptive OTFS that can change symbol length and other parameters in reaction to channel circumstances in real-time should be the focus of future studies.
