The purpose of the work is a comparative analysis of the potential interference immunity of separation-demodulation of two mutually non-orthogonal binary signals with opposite information states in the length of the information clock interval. Research methods – Probability theory, statistical theory of digital signal separation, numerical methods of multiple integration. Key words – mutually non-orthogonal digital signals, separation-demodulation algorithms, decision-making rule, error probability. The paper substantiates the expediency of applying the statistical theory of digital signal separation as a methodological basis for the synthesis and analysis of the potential interference immunity of the separation-demodulation algorithms of a small number of mutually non-orthogonal digital signals. An extensive method of synthesis of algorithms for coherent separation of two mutually nonorthogonal digital signals with binary modulation is presented for a number of initial conditions - synchronous and asynchronous according to clock points, with continuous and intermittent modes of radiation, with an arbitrary degree of non-orthogonality. The technique of analyzing the potential interference immunity of algorithms for coherent separation of two mutually non-orthogonal digital signals with binary modulation was further developed, calculations were performed and presented graphically. Formulated general conclusions based on the results of the work. The main claims are that successful separation-demodulation of mutually non-orthogonal digital signals is possible if the difference in instantaneous powers of mutually non-orthogonal signals to be separated is within 6-8 decibels Product Description popup.authors popup.nrat_date 2024-01-09 Close
