Abstract :
A perspective is given for maintenance of the requirements for interference defence in satellite communication systems, which is based on joint application of various ways of processing. The joint application of various kinds of processing permits us to overcome or to ease the number of basic restrictions which are inherent to separate methods and that application permits us to realize their potential possibilities. So, at the concurrence of the spatial spectrum of a useful signal and interference the efficiency of spatial methods of processing is low. Therefore interference suppression methods for signal processing using polarization distinction of a signal and interference are applied. The joint or combined application of processing methods permits us to provide a changing of modes of operations depending on the change of signal-interference conditions for the purpose of functioning with maximally possible quality
