FIELD: physics.
SUBSTANCE: spread spectrum signal is a broadening signal which modulates the carrier wave and which contains a real linear combination of the first signal transmitted at a first speed and a second signal transmitted at a second speed. The transmission speed of the first signal is different from transmission speed of the second signal and both speeds are not equal to zero. Linear combination of the first and second signals is modulated by at least one binary sequence which includes a signal identification code.
EFFECT: generation of a spread spectrum signal whose high level of spectrum regulation is combined with wider possibility of synchronisation.
