The relevance of the proposed study is determined by the fact that, in the context of the development of digital remote control systems for elements of the railway transport infrastructure based on 5G technology, the need for analyzing the transmission-reception channel and the operating principle of the energy detector has increased. The present paper proposes the test selection analysis for the type of input distribution in 5G channels. Purpose: to minimize the occurrence of collisions in communication channels that are the result of erroneous analysis of the input implementation. Methods: theoretical and empirical-analytical analysis of the efficiency of signal detection methods in case of intermittent transmissions. Results: the experiment was conducted with the objective of simulating random samples with a signal-to-noise ratio of no less than 10 dB in the channel. The probability of the correct decision on channel intermittency of no less than 0.7 obtained as a result of modelling confirmed the validity of choosing the Jarque–Bera test for analyzing channels with intermittent transmission. Conclusion and novelty: the author’s contribution to the issue under consideration is the development of a concept for conducting a preliminary analysis of the input implementation, with distribution indicators such as asymmetry and excess being taken into account. In the future, this will form the basis for constructing an adaptive energy detector that will operate according to the type of distribution of the processed implementation. Practical significance: the findings can be utilized to enhance the reliability and precision of energy detectors in wireless communication systems, particularly in scenarios where statistical data is limited and channel conditions are subject to change. It is evident that, given a priori information on signal distribution, the optimization of the detector setup process and the reduction of response time can be achieved.
