In this paper, we construct the autoencoder (AE) for optical wireless communication (OWC) systems with non-negativity and peak power constraints, which provides effective transceiver design in log-normal channel. We consider the cases where perfect channel state information (CSI) or noisy CSI can be...

Background/purpose: Oral squamous cell carcinoma (OSCC), a prevalent head and neck malignancy, is associated with poor survival rates in advanced stages. According to the American Society of Clinical Oncology (2023), the 5-year survival rate is 86 % for localized OSCC but drops to 69 % and 40 % for...
