Optic Communications, 286, 30-33. http://dx.doi.org/10.1016/j.optcom.2012.08.0840030-40181873-0310https://doi.org/10.1016/j.optcom.2012.08.084The average bit error rate (BER) of multi-Gaussian beams in non-Kolmogorov weak turbulence is examined. For each specific incidence of annular and flat-topped optical beam, a power law of non-Kolmogorov spectrum is found which is defined as the worst power law at which the average BER attains the maximum value. Using these values of the worst power laws, it is observed that thinner collimated annular, larger focal length annular and flatter small sized collimated flat-topped structures have a slight advantage in obtaining smaller average BER.
