Abstract

Abstract In this work, a 10 Gb/s–10 GHz hybrid orthogonal frequency division multiplexing (OFDM)-radio-over-free space optics (Ro-FSO) transmission link using 4-level quadrature amplitude modulation (QAM) has been modeled and its performance is investigated under different atmospheric conditions and system parameters. A link distance of 4000

at 10 Gb/s was achieved using the proposed link. Also, an improved performance by using a square root module (SRm) at the receiver end has been demonstrated. The results show a significant improvement in SNR and total received power using the proposed detection technique.
