“…FSO technology has numerous merits, such as quick and easy installation, high channel bandwidth, immunity to electromagnetic interference, a high-speed network, secure data transmission, and license-free spectrum availability [2][3][4][5]. Orthogonal frequency division multiplexing (OFDM) is a subset of multi-carrier modulation techniques using which a high-bit rate signal is transported over several low-speed subcarriers, which are spaced closely in the frequency domain and are orthogonal to each other, thus eliminating the intercarrier interference [6,7]. By incorporating OFDM technology with FSO links, highly reliable long-reach data transmission links can be realized.…”

Free space optics (FSO) has been recognized as a crucial technique to meet the high-bandwidth requirements in future wireless information transmission links. It provides a feasible solution to the last-mile bottleneck problem due to its merits that include high-speed data transportation and secure and low-latency networks. Due to these merits, FSO is a reliable technology for future health-care and biomedical services like the transmission of biomedical sensor signals. But the main limiting factor in the data transmission employing FSO links is adverse atmospheric weather conditions. This research work reports the designing and simulative evaluation of the performance of a high-speed orthogonal frequency division multiplexing–based free space optics link by incorporating wavelength division multiplexing of two independent frequency channels (193.1 THz and 193.2 THz) along with mode division multiplexing of distinct spatial laser Hermite–Gaussian modes (HG01 and HG03). Four independent 20-Gbps quadrature amplitude-modulated data signals are transported simultaneously under different atmospheric weather conditions using the proposed link. Also, the link performance has been investigated for an increasing beam divergence angle.

“…Analog network coding has been incorporated to provide enhanced throughput, power efficiency, and BER performance of the link. The incorporation of coherent detection technique in an OFDMbased FSO transmission is explored in [19]. 128 and 512 subcarrier transmissions were compared, and results indicated that the SNR performance of the link improves by 6 dB on increasing the number of sub-carriers.…”

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.
