| الوصف: | Currently, optical camera communication (OCC), as an emerging network access mode for the fifth-generation (5G), is valued for its advantages over radio frequency (RF). In the long-distance communication scenario, the data rate of line-of-sight (LOS) OCC is restricted. To address this, we propose a pilot-aided demodulation scheme to realize extending the communication distance, while also ensuring the data rate and reliability of the non-line-of-sight (NLOS) OCC. The experiment result validates the effectiveness of the proposed pilot-aided signal layer estimation (PSLE) and extreme value clustering (EVC) scheme, which can perform well against a heterogeneous background with ghost shadows at 2.5 m distance. |
