Abstract: The structure of the signal suppressed communication lines, where all parties are one and the same frequency band: the information signal is converted sequence Walsh, of a kind used for the separation of channels, and pseudo-casual sequence, which transforms an information signal in noise.
Shows the structure of the system for effective suppression of the transmitted information: frequency of the communication channel and a specific code combination (code Walsh) in the direct channel of communication of information.
Developed structure of the device synchronization suppressed signal interference.
Key words: noise immunity, satellite communication systems, encoded channel separation, noise-like signal, a signal with distributed spectrum, multi-access, pseudo-random sequence.
