“…Also monitoring of the water quality in ishing farms is another application that is highly important for timely process of growing ishes. A very main case of industrial application is oil exploration wherein the the real-time monitoring of the oil pipelines in the depth of water is carried out by IoUT [40]. This applications are further boosted by using underwater multimedia systems by acoustic waves for acquisition of image and video and their classiication [39].…”

Telecommunications systems with Multi-Input Multi-Output (MIMO) structure using Orthogonal Frequency Division Modulation (OFDM) has a great potential of efficient application to a network of Internet of Things (IoT) of a high data rate. When the IoT network is amongst the underwater sensory devices known as the Internet of Underwater Things (IoUT), the electromagnetic wave can not play the role of baseband signal due to rapid fall off inside the water. Thus, Acoustic OFDM is a reliable replacement for conventional OFDM inside the water. A blind structure for MIMO acoustic OFDM using Independent Component Analysis (ICA) brings even further advantages in data rate and energy consumption by avoiding the required pilot and preamble data. This research work presents a blind MIMO Acoustic OFDM blind transceiver for IoUT based on Probabilistic Stone’s Blind Source Separation (PS-BSS). The proposed technique has multiple times lower complexity compared to the ICA-based technique while maintaining a comparable efficiency. As observed in the results carried out one hundred Monte Carlo runs of transmission random data bits, over a highly sparse channel that is the common case of an underwater environment the proposed PS-BSS-based technique dominates the ICA-based one, and as the sparseness of the channel decreases its efficiency is comparable to ICA-based technique. Thus in the case of a high sparse channel, the proposed technique is superior in both aspects of efficiency and complexity while over lower sparseness due to its comparative efficiency it can be hired as an optimum technique fulfilling a fair trade-off between efficiency and complexity.

“…Dominancy of scintillation noise variance comparing with shot and thermal noise variances is showed in Eyyuboglu and Bayraktar (2015). Similarly, effect of underwater turbulence is tested via transmitting video (Priyalakshmi and Mahalakshmi 2020). On the other hand, possible data rates can reach up to 3.84 Tbps with distance 58,000 km since there is no turbulence between satellites (Sumathi et al 2020).…”

We present on-axis, aperture averaged scintillation, and bit error rate performance of Mathieu-Gauss beams (MGB). We model atmosphere utilizing random phase screen. Our investigations show that scintillation indexes of both odd and even modes of MGBs are less than Gauss beam. In the comparison of odd and even modes, odd modes draw the attention with its less scintillation index. In case of aperture averaged scintillation, all types of MGBs are advantageous comparing with Gauss beam but this advantage vanishes with increase in receiver aperture opening. Mitigation in scintillation index brings us 10 −6 times lesser bit error rate (BER) than Gauss beam.

“…Great improvement can be obtained using Mathieu-Gauss beam on the source plane (Bayraktar 2020). In addition, BER of an underwater optical communication system is reduced using Hermite-Gaussian beam (Priyalakshmi and Mahalakshmi 2020). Another way to improve the performance of optical wireless communication systems is the application of different modulation types (Sumathi et al 2020).…”

We study scintillation and bit error rate performance of mirrored Bessel beams through turbulent atmosphere in this article. We benefit from numerical method to model the atmosphere. Since scintillation plays a vital role in optical wireless applications, reduction in this term provides better performance in these systems. Bearing in mind this, our results indicate that it is possible to decrease scintillation by increasing beam order to three when strong turbulent conditions are satisfied. In addition, we observe that argument of Bessel beam has more dominant role than beam order in moderate turbulence. Lastly, mirroring brings us a slight advantage in case of bit error rate. Results of this study can be beneficial for optical link designers.
