Free-space optical communication employing subcarrier modulation and spatial diversity in atmospheric turbulence channel [PDF]

, 2008
An expression for the bit error rate of a multiple subcarrier intensity-modulated atmospheric optical communication system employing spatial diversity is derived. Spatial diversity is used to mitigate scintillation caused by atmospheric turbulence, which

Prediction of Aerosol Extinction Coefficient in Coastal Areas of South China Based on Attention-BiLSTM

Journal of Marine Science and Engineering, 2022
The aerosol extinction coefficient (AEC) characterises the attenuation of the light propagating in a turbid medium with suspended particles. Therefore, it is of great significance to carry out AEC prediction research using state-of-art neural network (NN)
