This paper addresses the impacts of biasing and clipping on free-space optical (FSO) communications system over weak turbulence channel employing direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM). With atmospheric attenuation, turbulence and pointing errors, we present a statistical model for the optical intensity fluctuation at the receiver. The average bit error rate (BER) performance is analyzed in the channel environment and a theoretical expression is… CONTINUE READING
