We propose an optical watermarking strategy based on precise bias tuning of an electro-optical modulator and a convolutional neural network-enabled decoder. This scheme can be used for identity aut…
In this paper, we report a novel indoor optical wireless communications system employing orbital angular momentum (OAM) mode-based beam shaping. Different shapes of transmitted beams with various p…
In this paper, we proposed an improved mobile fronthaul architecture employing the SNR-improved delta-sigma digitization scheme and 4-level pulse amplitude modulation (PAM-4) format. Different from…
