Channel modeling for optical wireless communication through dense fog

Feature Issue on Optical Wireless Communications (OWC) The modified vector radiative transfer equation is solved in the frequency domain to study the frequency response of the propagation channel. In the time domain, the impulse response is obtained by taking the inverse Fourier transform of the frequency response. The time-domain analysis investigates the effects of the receiver's field of view on reducing the bit error rate when there is intersymbol interference caused by the temporal spread of the received signal.
