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.
