Comparison Study of Time Synchronization in NC-OFDM Systems Based on Symmetric Correlator

Jurnal Elektronika dan Telekomunikasi, 2019
NC-OFDM as one of the candidates for the Cognitive Radio (CR) system has many challenges in the synchronizing time. This is due to the frequency sharing which can cause Narrowband Interference (NBI), which causes a very significant time synchronization ...

Impact of Narrow Band Imaging in Pre-Operative Assessment of Suspicious Oral Cavity Lesions: A Systematic Review [PDF]

Iranian Journal of Otorhinolaryngology, 2021
Introduction: Narrow band imaging (NBI) is a powerful tool that allows visualizing the mucosal and submucosal vasculature. Among the available diagnostic techniques, NBI is one of the most valid for early detection of oral squamous cell carcinoma (OSCC).
