“…[1][2][3] Call for higher speed in mobile communications is inspiring the disposition of new and innovative technologies, which are often associated with radical changes in radiofrequency (RF) signal formats. A new wireless optical technique known as radio over free space optics (RoFSO) is being developed which combines RoF and FSO techniques 6,7 to provide short-range broadband communication at places where fibre installation is not possible and in disaster prone areas. Also, the use of frequency reuse concept is advised, but this upsurges the infrastructure cost as more and more base stations have to be positioned.…”

“…The principle being the dispersion induced losses in fibre including fading of signal and walk off effect. A new wireless optical technique known as radio over free space optics (RoFSO) is being developed which combines RoF and FSO techniques 6,7 to provide short-range broadband communication at places where fibre installation is not possible and in disaster prone areas. RoFSO uses free space as the channel unlike RoF which uses fibre.…”

This paper improves the performance of 60-GHz wireless optical system including radio over fibre (RoF) and radio over free space optics (RoFSO), based on novel reverse-parallel (RP) hybrid modulation scheme. This scheme combines the chromatic dispersion compensation technique of parallel modulation with energy efficiency manipulation technique of reverse modulation.Superior functioning of RoFSO is provided with reverse modulation compared with normal modulation. Comparative investigations are performed by loading 60-GHz RF signal with 2.5 and 10-Gbps data and modulating it with both reverse and hybrid modulators. Hybrid modulation performed better with improved BER of 10 −23 at distance of 51 km for 2.5-Gbps data compared with reverse modulation with BER of 10 −7 .
