The analysis of up-to-date communications shows, that problem connected with difficult interference situation is mostly apparent for geostationary telecommunication systems. The reason of this is in high density of communication spacecrafts at geostationary orbit. The ITU standards recommend having 3 angular degrees between adjacent spacecrafts to allow its normal functioning in terms of mutual interference. However, by results of analyzing of the tendencies in current satellite market, as well as satellite-s operators requirements to up-to-date domestic and foreign, spacecrafts, it is possible to realize that now satellites are placed by 3 in one orbital slot, in case of coordination of orbital frequency resource. The great growth of satellite communication systems number, in aggregate with limited orbital frequency resource, lack of free geos-tationary orbital slots, intensive development of premeditated influence systems have impact on effectiveness of current satellite signals receiving and processing tools. So, the actual task of improvement of satellite communication systems quality is appeared. This task is solved due to development of methods of robust signals forming and receiving algorithms optimization.
