Abstract

Due to the increased demand for data rate, flexibility, and reliability of 5G cellular systems, new modulation formats need to be considered. A recently proposed scheme, Orthogonal Time Frequency Space (OTFS), offers various advantages in particular in environments with high frequency dispersion. Such environments are encountered, e.g, in mm-wave systems, both due to the higher phase noise, and the larger Doppler spreads encountered there. The current paper provides a performance evaluation of OTFS at 5G mm-wave frequencies. Comparisons with OFDM modulation show that OTFS has lower BER than OFDM in a number of situations.
