Abstract. The periodical vary of signal and noise situation` influence on data link layer and network layer parameters of communication channel in the conditions of adaptive ways of selection of signal` modulation and type anti–interference coding` rate are introduced in the article. The transfer capability and the time delay were researched as data link layer parameters. The metric of communication channel and the intensity of messages of its variation were researched as network layer parameters. The objects of research are satellite communication channels, which use DVB–S2 and DVB–S standards in SCPC, MCPC with TDMA and MCPC with S–Aloha behavior.

Key words: DVB–S, DVB–S2, anti–interference, noise immunity, communication channel, noise protection, signal and noise situation, metric of network, network layer parameters, transfer capability, radio rejection.
