“…Yang et al proposed an ellipse Gaussian model to represent localized deformation. Based on the ellipse Gaussian model, Yang et al investigated the influence of localized wavefront deformation on optical communication system performance, which contains the received power, mutual alignment error, Strehl ratio [9][10][11], etc. Nevertheless, the realistic deformation is caused by various factors, and it tends to be diversified instead of symmetrical Gaussian.…”

Diversified wavefront deformation is an inevitable phenomenon in intersatellite optical communication systems, which will decrease system performance. In this paper, we investigate the description of wavefront deformation and its influence on the packet error rate (PER) of digital pulse interval modulation (DPIM). With the wavelet method, the diversified wavefront deformation can be described by wavelet parameters: coefficient, dilation, and shift factors, where the coefficient factor represents the depth, dilation factor represents the area, and shift factor is for location. Based on this, the relationship between PER and wavelet parameters is analyzed from a theoretical viewpoint. Numerical results illustrate the validity of theoretical analysis: PER increases with the depth and area and decreases if location gets farther from the center of the optical antenna. In addition to describing diversified deformation, the advantage of the wavelet method over Zernike polynomials in computational complexity is shown via numerical example. This work provides a feasible method for the description along with influence analysis of diversified wavefront deformation from a practical viewpoint and will be helpful for designing optical systems.
