A variant of constructing an error flow simulator in a sequence of data transmitted over the radio channel using a signal with quadrature phase manipulation is proposed. The developed simulator takes into account the features of the implemented in practice coherent reception of signals with multi-position phase manipulation in the transmission of data in a digital communication channel. The adequacy of the results obtained by its use is confirmed in the process of modeling data transmission in a limited frequency resource channel. The expediency of using the proposed error flow simulator is due to the possibility of correlating the error flow parameters with the technical characteristics of the data transmission system and the intensity of interference in the radio channel.
