•Scintillation characters of PBSM beams is analyzed with wave optics simulation.•The modified phase screen approach is taken here to create the PBSM beams.•The evolution of PBSM beams is based on the Multi-phase screen method.•Findings show that the PBSM beams are resistant in the strong fluctuation regime. The scintillation index of pseudo-Bessel-Gaussian Schell-mode (PBGSM) beams propagating through atmospheric turbulence is analyzed with the help of wave optics simulation due to the analytic difficulties. It is found that in the strong fluctuation regime, the PBGSM beams are more resistant to the turbulence with the appropriate parameters β and δ. However, the case is contrary in the weak fluctuation regime. Our simulation results indicate that the PBGSM beams may be applied to free-space optical (FSO) communication systems only when the turbulence is strong or the propagation distance is long.
