Effects of Backscattering and Atmospheric Scintillation on OFDM Based Optical Wireless Communication
並列摘要
Orthogonal frequency division multiplexing (OFDM) based optical wireless communication (OWC) is a viable technology and has been widely applied in indoor as well as outdoor communication. Atmospheric scintillation and backscattering are the main impairments in OWC. Orthogonal Frequency Division Multiplexing (OFDM) has been widely used in the optical wireless communication. Nevertheless, due to both frequency offset and phase noise, the performance of OFDM can severely be affected. The combined effect of atmospheric scintillation, backscattering, frequency offset and phase noise has been investigated in OFDM based OWC. As the value of backscattering power and atmospheric scintillation increase, the BER also increases and thus degradation of performance occurs.
