“…A novel hybrid PDM-OFDM model is proposed using OptiSystem in [15] with improved performance increasing the user capacity, SE and reducing multipath fading for FSO transmission system. In [16], a PDM-CO-OFDM FSO communication system is introduced to reduce the influence of scintillation through atmospheric FSO channel resulting in long distance propagation under strong turbulence as depolarizing property is weakest in the atmosphere.…”

A comprehensive novel design is proposed for the free-space optical (FSO) communication system by hybridizing circular polarization division multiplexing (CPDM) with coherent optical orthogonal frequency division multiplexing (CO-OFDM) and its performance is investigated realistically under diverse turbulent weather conditions of Bangladesh. Here we consider Gamma-Gamma (G-G) distribution for the turbulent FSO channel model. Moreover, the proposed scheme presents an excellent performance since CPDM technique not only maximizes the link capacity of FSO system but also enhances the spectral efficiency (SE) of the system. Besides, multipath-fading, which is appeared during the FSO transmission, is significantly mitigated by OFDM modulation. The outcomes from simulation confirm the advantages of the proposed hybrid scheme and also it can serve as a reference for the FSO application even in the turbulent weather conditions. Performance analysis of the proposed model is described in terms of optical power spectrum (OPS), optical signal to noise ratio (OSNR), bit error rate (BER), Q factor, constellation diagrams, and eye diagrams.

“…Wavelength division multiplexing (WDM) is an important technology in which multiple data signals are transported simultaneously over the same channel using different optical beams from distinct laser source to realize a high-speed information transmission link [21,22]. In WDM systems, multiple information signals from different transmitter sections each using a distinct laser source are combined using a WDM multiplexer (MUX), and then the multiplexed signal is transmitted through free-space channel.…”

A 4 × 20 Gbit/s-40 GHz orthogonal frequency-division multiplexing-based radio-on-free-space optics information link, integrating hybrid wavelength- and mode-division multiplexed transmission techniques, is proposed in this paper. Furthermore, an ameliorated detection scheme deploying a square root module after each photo diode at the receiver terminal is proposed to mitigate the adverse performance effects because of nonlinear photodiode characteristics. The presented results show a successful 80 Gbit/s-160 GHz transmission at 3000 and 2700 m under heavy rainy and foggy weather, respectively. The link demonstrates superior performance in terms of maximum range and transmission rate compared to previous works.
