Abstract: The orthogonal time-frequency-space modulation technique proves to be a promising modulation scheme for beyond-5G communication systems. Its notable advantage lies in achieving a low bit error rate in the delay Doppler region, which is a significant improvement over traditional 5G OFDM systems that are prone to problems such as high BER and multipath fading. Our research focuses on modeling BER for OFDM and OTFS with the aim of conducting a comprehensive comparison of their performance. Our results show that OTFS consistently exhibits reduced BER in contrast to standard OFDM systems. This shows the potential of OTFS for more reliable communications, especially in scenarios where traditional OFDM systems encounter challenges related to errors and fading effects. This paper summarizes our efforts to highlight the benefits of adopting OTFS modulation for the development of robust and efficient communication systems in the future.
