description: The object of research is combinations of different cascaded block codes and different modulations. The purpose of the work is to determine the most efficient coding and modulation scheme according to the criterion of minimum ratio of the information bit energy to the spectral density of the average noise power for a given error probability per packet. As a result of the study, several mathematical models of wireless communication systems for packet transmission in a channel with conditions typical of the space environment were built in the MATLAB package. The models vary in coding schemes, digital modulation, and packet sizes. Graphs of packet error probabilities for communication systems with different parameters are obtained, the result of the work is an analysis of noise immunity and a decision on the most effective concatenated coding scheme from those presented according to the criterion of error probability per packet. The terminological features of the subject area are taken into account and software tools are used to solve problems. Specialized MATLAB software was used.
