Abstract

Summary

Synchronization in the time-frequency domain for the fifth-generation (5G) new radio (NR) takes the fundamental steps
as in all mobile networks to have user equipment (UE) properly receive and transmit data. The corresponding
synchronization for 5G has various challenges due to the wide range of frequencies. This is more so when it comes to
applications that would need accurate oscillators to reduce the large values of the frequency offset. This paper presents
challenges and issues within the 5G NR synchronization specifically on the pilot-based time and frequency
synchronization for OFDM and UFMC systems. It also compares cyclic prefix (CP) based synchronization as it applies to
OFDM systems with UFMC noting that no CP is inserted in UFMC system. The effect of timing and frequency offset on
OFDM and UFMC systems is then presented with two approaches, CP-based and pilot-based synchronization. Simulation
results of the synchronization performance shows that the UFMC out performs OFDM making it more adaptable to 5G
considerations.
