Abstract. This article considers the radio link of satellite communication with signal processing on board of the communication relay, "soft" decisions at the input of the decoder, coherent reception, the perforation of affected symbols (blocks) in the combined use of codes with the low density of parity check (LDPC) and the methods of multiposition manipulation in the conditions of the impact of willful interference.
Key words and phrases: радиолинии спутниковой связи, частотно-энергетическая эффективность, помехозащита, сигнально-кодовые конструкции, ретранслятор связи, radio links of satellite communication, frequency-energy efficiency, anti-jamming, signal-code sequences, communication relay.
