“…Gurjit et al propose [ 238 ] a hybrid Polarization Division Multiplexing (PDM)/OFDM, which sends different signals over orthogonal states of polarization by a polarization splitter that splits the optical signal into two polarized orthogonal signals which are carrier and modulated data of users, this method boosts the transmission effectiveness. Both orthogonal signals are split and demodulated to retrieve the original signals at the destination.…”

Increased capacity, higher data rate, decreased latency, and better service quality are examples of the primary objectives or needs that must be catered to in the near future, i.e., fifth-generation (5G) and beyond. To fulfil these needs, cellular network design must be drastically improved. The 5G cellular network design, huge multiple-input multiple-output (MIMO) technology, and device-to-device communication are all highlighted in this comprehensive study. Hence, free-space optics (FSO) is a promising solution to address this field. However, FSO standalone is insufficient during turbulent weather conditions. FSO systems possess some limitations, such as being able to be disturbed by any interference between sender and receiver such as a flying bird and a tree, as it requires line-of-sight (LOS) connectivity. Moreover, it is sensitive to weather conditions; the FSO performance significantly decreases in bad weather conditions such as fog and snow; those factors deteriorate the performance of FSO. This paper conducts a systematic survey on the existing projects in the same area of research such as the hybrid FSO/Radio frequency (RF) communication system by listing each technique used for each model to achieve optimum performance in terms of data rate and Bit Error Rate (BER) to be implemented in 5G networks.

This article reports the free space optics (FSO) with generation of a high bit rate transmission link with 16 QAM phase shift keyed signals. Optical receiver is proposed to mitigate the performance of demodulator under environmental conditions. Also, to resolve the adverse channel effects on the information signal digital signal processing (DSP) techniques at the receiver end are used. The bit error rate (BER) analysis using numerical simulations for divergent weather conditions is bring out and the results illustrate 112 Gbps transmission link. Further, the comparison is conducted with previous techniques which shows that the system provides better data rate performance and achievable range. The reported work provides a suitable reference towards optical communication under different environmental conditions.

“…Besides, robustness against channel fading effects can also be further improved using coherent scheme [14]. 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.
