Since the direct-gradient (DG) method uses the Shack-Hartmann wave front sensor (SH-WFS), based on the phase-conjugation principle, for atmospheric compensation in free-space optical (FSO) communication, it cannot effectively correct high-order aberrations. While the stochastic parallel gradient descent (SPGD) can compensate the distorted wave front, it requires more calculations, which is sometimes undesirable for an FSO system. A hybrid compensation (HC) method is proposed by properly using the DG method and SPGD algorithm to improve the performance of FSO communication. Simulations show that this method can well compensate wave-front aberrations and upgrade the coupling efficiency with few computations, preferable correction results, and rapid convergence rate.

“…This effect can be quantified by propagating the field at the aperture of the transmitter to the aperture plane of the receiver through Fraunhofer's diffraction. Yang et al 111 analyzed the impact of the transmitter WFE in an FSOC communication link using on-off keying modulation. This analysis shows that for the same root-mean-square value of the primary aberrations, coma aberration will have the largest impact while spherical aberration the least.…”

“…Usually, these two effects created by thermo-mechanical loads on the satellite are small enough that the spot remains contained within the detector. 69,111 However, when the incoming beam is coupled into a fiber [see Fig. 12(c)], the WFE induced by the thermo-mechanical phenomena in the receiver terminal will decrease the coupling efficiency.…”

Growing interest in free-space optical communication, due to the high bandwidth and security provided by these links, has generated the necessity of designing high-performance satellite terminals. In order to develop these terminals, the optothermo-mechanical phenomena that appear in the space environment and their effect on optical communication links have to be understood in detail. A review of the opto-thermo-mechanical phenomena occurring in spaceborne terminals is presented, describing the relevance of each of them. The methods found to compute the impact on the communication performance due to opto-thermo-mechanical phenomena are collected by building the bridge between the optical and communication performance parameters. Finally, techniques available to mitigate the detrimental effects of these phenomena are classified, and the relevant research challenges are identified.

“…With increasing demands for real-time communication throughout the world, intersatellite optical networking communications have attracted considerable attention for potential high-speed data rate and global coverage access [1][2][3][4][5][6]. The channel capacity, according to the Shannon theorem, is the maximum achievable code rate allowing reliable communication between transmitter and receiver [7][8][9].…”

This work is motivated by the need to achieve the Shannon channel capacity for intersatellite optical communication with intensity modulation and direct detection. In this paper, we investigate the tradeoff between the channel capacity and the outage probability in the presence of random pointing jitter for intersatellite optical links. First, we derive an analytical expression of the outage probability in the absence of bias error, and then the bias error is taken into account. By minimizing the outage probability, we obtain analytically the optimum design of the beam half-width divergence angle w opt 0 for a given channel code rate. Furthermore, we discuss the tradeoff between the outage probability and the channel capacity and illustrate the results by adopting w opt 0 in the presence of random pointing jitter. The results obtained are useful for the parametric-estimation optimization of intersatellite optical communication systems.
