Using the methods of numerical experiment, the analysis was performed of a device, intended for detection of an optical vortex topological charge and functioning of a communication line, based on this detector. Investigations were carried out, taking into account turbulent distortions of receiving radiation. Probability of error appearance was assessed as a function of turbulence intensity, and interval of parameters was found, where the quality of detection is high. The assumption, stated in our previous papers, was confirmed of independence of the detection quality on the path length.
