Progress in optical wireless communication (OWC) has unleashed the potential to transmit data in an ultrafast manner without incurring large investments and bulk infrastructure. OWC includes wireless data transmissions in three optical sub-bands; ultraviolet, visible, and infrared. This paper discusses installing infrared OWC, known as free space optics (FSO), systems on top of installed radio frequency (RF) networks for outdoor applications to benefit from the reliability of RF links and the unlicensed broad optical spectrum, and the large data rates carried by laser beams propagating in free space. We equally review commercially available solutions and the hardware requirements for RF and FSO technology co-existence. The potential of hybrid RF/FSO for space communication is further discussed. Finally, open problems and future research directions are presented.

“…R ECENT years, satellite communication (SatCom) has been the key part of fifth-generation (5G) networks and beyond 5G (B5G) networks due to its inherent characteristics such as high throughput, wide coverage, high reliability, and disregarding geographic boundaries for propagation, which will be an excellent complement to the current terrestrial communications [1]- [4]. Therefore, incorporating SatCom into existing terrestrial communication systems has become mainstream research today, which is the basic architecture of integrated satellite terrestrial networks (ISTNs) [5]- [7].…”

Integrated satellite terrestrial networks (ISTNs) are becoming a hot research topic in recent years due to the capabilities of high quality, high throughput, and seamless coverage. However, the limited spectrum resources are difficult to meet the needs of a large number of users in ISTNs, and the obstacles and shadowing will seriously affect the communication quality of networks. In this regard, cooperative transmission of non-orthogonal multiple access (NOMA)-assisted ISTNs with the help of multiple terrestrial relays are established to enhance the spectrum efficiency and enlarge the transmission coverage. In this paper, we investigate the performance of NOMA-based ISTNs with relay selection and imperfect successive interference cancellation (SIC). Particularly, the partial relay selection (PRS) scheme is used in the considered system to reach the balance of system performance and complexity. Owing to practical constraints, the imperfect SIC is analyzed for the networks. Based on the PRS scheme and imperfect SIC, we obtain the closed-form expressions for the outage probability (OP) and ergodic capacity (EC) of the considered networks. Besides, to get further insights of key system parameters, the asymptotic analysis for the OP is also derived. Finally, numerical and simulation results are presented to validate the correctness of our analytical results. INDEX TERMS Integrated satellite terrestrial networks (ISTNs), non-orthogonal multiple access (NO-MA), relay selection, successive interference cancellation (SIC).

In this paper, we investigate the uplink transmission in a satellite-aerial-terrestrial network (SATN), where an aerial platform acts as an amplify-and-forward relay assisting the communication between multiple users and satellite. The users send messages to the aerial relay via radio frequency (RF) links, which are then forwarded to the satellite through a free-space optical (FSO) link. By assuming that the angle-of-arrival based imperfect channel state information of each user is known at the aerial platform, we propose a beamforming scheme to maximize the minimum average signal-to-interference-plus-noise ratio of the users. Due to the mathematical intractability, we design an iterative algorithm to obtain the optimal beamforming vector for the RF link. Furthermore, by considering that the FSO link experiences the Málaga fading with non-zero boresight pointing error and the RF links follow Nakagami-m fading, we derive an analytical expression for the outage probability of the considered SATN. Finally, computer simulation is conducted to validate our theoretical analysis. It is shown that the proposed algorithm can improve the system performance and robustness compared to existing works. Index Terms-Mixed RF-FSO channels, uplink transmission, outage probability, robust beamforming, satellite-aerialterrestrial network.
