Influence of beam wander on bit-error rate in a ground-to-satellite laser uplink communication system

Abstract

Based on weak fluctuation theory and the beam-wander model, the bit-error rate of a ground-to-satellite laser uplink communication system is analyzed, in comparison with the condition in which beam wander is not taken into account. Considering the combined effect of scintillation and beam wander, optimum divergence angle and transmitter beam radius for a communication system are researched. Numerical results show that both of them increase with the increment of total link margin and transmitted wavelength. This work can benefit the ground-to-satellite laser uplink communication system design.

High-data rate differential phase shift keying receiver for satellite-to-ground optical communication link

“…While the MZI-DPSK receiver can eliminate the noise phase caused by atmospheric turbulence, it cannot inhibit effectively the intensity fluctuation caused by beam wander [19] , arrival-of-angle fluctuation and scintillation [20] . The experimental results confirm that the stability of Eye-diagram for the MZI-DPSK receiver is deteriorated when the turbulence structure profile 3.…”

Beam wander of Gaussian-Schell model beams propagating through oceanic turbulence

“…Turbulence causes optical propagation phenomena such as diffraction, scattering, absorption, and beam wander that attenuate or diffuse the signal of the communication system through stochastic processes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. When a light beam propagates in a turbulent atmosphere or turbulent ocean, it experiences random perturbations that tend to deflect the beam to one side or the other of the path that the beam would have taken had it propagated in a vacuum.…”

“…This effect is known variously as beam wander, beam steering, or spot dancing [1]. Recently, the beam wander caused by terrestrial atmospheric turbulence, which induced scintillation [2] and irradiance distribution [3,4] are of great significance, in the ground-to-satellite laser communication has attracted lots of attention [5][6][7][8][9][10]. Under weak turbulence conditions, the model of long term beam spread, beam wander and Strehl ratio of a Gaussian beam wave propagating through maritime atmospheric turbulence has been analyzed [11].…”
