According to Euroconsult report there were launched 100 telecommunication satellites in 2011, in 2012 - 84 satellites and in 2013 - 98 satellites. Herewith, it is expected that 267 satellites will be launched by 2015. From 2013 to 2018 the cumulative increase of mobile satellite communication users - number will be 20%. Increasing number of satellite communication systems (SCS) together with limitation of orbital frequency resource, increase of transmitted information volume, absence of free geostationary positions predetermine problems in SCS effective functioning ensuring in conditions of complicated radio electronic situation. All of stated above formulates the actual science problem. This problem is to develop methods for increase of satellites communication and retranslation systems effectiveness. In the article the method of generating the wavelet modulated broadband signal, permitting to increase the resistance of communication system to jamming, is proposed. The algorithm of communication system adaptation to narrowband and broadband malicious interferences is described. By results of computer simulation the effectiveness of proposed communication system adaptation algorithm by influence of the narrowband and broadband malicious interferences is corroborated.
