“…This has driven recent research in satellite communications into the study of provisioning high bandwidth feeder links. Since the limited spectrum available in Ku-Ka bands may not be sufficient to ensure Terabit/s communications by means of efficient frequency reuse alone, most feeder link studies focus on moving to higher frequency bands (Radio Frequency (RF) bands like Q/V (40/50 GHz), [3][4][5][6] W (70/80GHz) 7 or even Optical. [8][9][10] Free Space Optics (FSO) communications represent an interesting alternative due to the following advantages over RF:…”

In this paper we exploit the transmitter micro diversity in the satellite communication systems with optical feeder links. Both analogue and digital transparent systems are studied. We consider up to four statistically independent transmitted optical beams with perfect or partial phase knowledge of the beams at the receiver. End-to-end simulation results for frame error rates are presented for a complete system including uplink, satellite payload and downlink. We compare our results with those of the DVB-S2 standard without the optical feeder link. Our results provide a complete view of gains and losses which can be obtained by micro diversity in both analogue and digital transparent satellite systems with optical feeder link. Given the system parameters, we also provide a detailed study of the transmitted power needed to achieve a target frame error rate and discuss the achieved bit rates in for each system scenario.

Summary Data relay satellite (DRS) systems play an important role in space information networks. Characterized by highly dynamic topology and discontinuous communication links, it is suggested that the IEEE 802.11 protocol employed in such a network could be more flexible. However, such a terrestrial network protocol could not be applied to DRS systems directly, nor supports a fast response due to the long propagation delay and severe packet collision. To address this challenge, we proposed an enhanced media access control (MAC) protocol based on the IEEE 802.11 protocol providing multiaccess for low earth orbit (LEO) distributed constellations. In this paper, we investigated the access delay performance of the proposed protocol in our model. Then, we derived a contention window adaption by using an iteration algorithm that can dynamically adjust the values of the contention window depending on the number of user satellites in the communication coverage. Simulation results show that the average access delay does not exceed 20 seconds, which is significantly lower than the standard protocol. Moreover, the traffic threshold is increased to 0.6, and the maximum throughput has doubled compared with the standard protocol. It is proved that the enhanced MAC protocol shows a better performance in DRS systems.

“…The long-haul communication systems, such as the Ka-band high throughput satellites and free-space optical communications, can offer ultra high-speed data transfer rates by using millimeter wave even optical wave. However, such extreme short waves often suffer from burst errors due to the signal loss by air turbulence, clouds or precipitation and solar wind [1], [2]. The burst error channels can be modeled as a two-state Markov model called Gilbert-Elliott model, which is defined in [3].…”

The long-haul communication systems can offer ultra high-speed data transfer rates but suffer from burst errors. The high-rate and high-performance staircase codes provide an efficient way for long-haul transmission. The staircase coding scheme is a concatenation structure, which provides the opportunity to improve the performance of high-rate polar codes. At the same time, the polar codes make the staircase structure more reliable. Thus, a high-rate polar-staircase coding scheme is proposed, where the systematic polar codes are applied as the component codes. The soft cancellation decoding of the systematic polar codes is proposed as a basic ingredient. The encoding of the polar-staircase codes is designed with the help of density evolution, where the unreliable parts of the polar codes are enhanced. The corresponding decoding is proposed with low complexity, and is also optimized for burst error channels. With the well designed encoding and decoding algorithms, the polar-staircase codes perform well on both AWGN channels and burst error channels.
