ASYMPTOTIC METHODS AND RESULTS OF ANALYSIS OF PROTOCOLS carrier sense multiple access with conflict detection about conflict resolution at the physical layer Object of study - algorithms for the operation of wireless systems with random multiple access. The subject of the study - methods of protocol analysis in radio systems with random multiple access. The work is aimed at solving a scientific task, the essence of which is to evaluate the efficiency of wireless multiple access random communication systems, which can be used to develop a tactical task for the Ukrainian industry and to create a promising mobile component of the State Secretariat of Communications of Ukraine. The purpose of the work is to estimate the bandwidth and average time before successful servicing on casual multiple access systems with the additional assumption of physical-level conflict resolution, ie in demodulators of receiving devices. Research methods - asymptotic analysis in queuing theory, statistical methods in multiplayer detection theory. As a result of the research, the following were obtained: • methods and results of analysis of a family of random multiple access protocols with non-seed control and conflict detection with the additional assumption of resolving multiplicity 2 and 3 conflicts at the physical level; • methods and results of statistical synthesis of demodulation procedures for mutually non-orthogonal digital signals with angular modulation types.
