FIELD: electrical communications. SUBSTANCE: control and interaction signals are transmitted together with group eight-channel digital stream at 256 kbit/s with adaptive differential pulse-code modulation. Signal receiver has matching unit 1, first and second main storage units 2, 3, address switch 4, master oscillator 5, reference train shaper 8, correlometer 9, signal sine component adder 10, signal cosine component adder 11, computer unit 12, resolving unit 13, adaptive code register 14, threshold code comparator 15, OR gate 16, and output register 17. EFFECT: improved noise immunity, enlarged dynamic range of passband reception level and regulation range.
