Curved OLED-based NLOS optical camera communications links

Popis výsledku v původním jazyce

In this paper, for the first time, to the best of our knowledge, we experimentally demonstrate the use of a curved organic light emitting diode (OLED) as a transmitter (Tx) in the non-line-of-sight (NLOS) optical camera communication (OCC) link for an indoor environment using a camera as a receiver. The proposed NLOS-OCC scheme is evaluated for the signal-to-noise ratio (SNR) and the reception success rates ????rs under key photographic and communication parameters, including exposure times ????exp and gain values ???????? , as well as the transmission frequency ???????? and the distance ???? . The SNR analysis is performed using a binary classification procedure based on a Gaussian mixture model for the first time, to the best of our knowledge, for OLED-based NLOS-OCC links. We also derive and demonstrate that the effect of ???????? on the SNR with respect to ???? is minimal based on the pixel illumination model. The initial analysis suggests that, for a wall reflector-based NLOS-OCC link that is 2 m long, the SNR and ????rs increase by 1 dB and 4% (83–87%) for ???????? of 600 Hz, with an increase in ????exp of 1000–1500 µs and ???????? of 25–45 dB.
