Abstract

We report the simulation-modelling and evaluation of an integrated Orthogonal-Frequency Division Multiplexed (OFDM)-Mode-Division Multiplexed (MDM) Radio-on-Free Space Optics (Ro-FSO) scheme carrying 2-independent 40 GHz millimetre waves (mm Wave) at 20 Gbps per channel for 5th generation wireless applications. The reported Ro-FSO scheme transports 2-independent 20 Gbps 4-Quadrature-Amplitude Modulated (4-QAM) signals, each carrying 40 GHz mm Wave signal over 2-distinct Laguerre-Gaussian (LG) modal beams and their performance evaluation is carried out for varying levels of clear and foggy weather. Also, we have taken into consideration the effect of increasing size of optical beam signal on the reported scheme performance. The reported results elucidate favourable transportation of both mm Wave signals along 40 km range for clear sky and 1.5 km for heavy-foggy weather.
