The promising spectrum sharing technology used to improve the spectrum usage may cause severe narrowband interference, which seriously degrades the timing synchronization. As noticed that only the auto-correlation based methods have been investigated in the literature, this paper examines the impairment of narrowband interference to the cross-correlation based timing synchronization, to obtain a comprehensive...
Spectrum sharing is promising to improve the efficiency of spectrum usage. However, this technology may incur severe narrow band interference (NBI), which seriously complicates the synchronization problem. This paper investigates the timing synchronization problem in the presence of NBI for the OFDM-based spectrum sharing systems. We consider the cross-correlation based timing synchronization and...
