Research of efficiency of use of digital processing in satellite communication systems

Prospects of use of digital processing of signals in satellite communication systems are considered. It is shown that digital processing allows to enlarge an energy potential of radio lines and to increase the general throughput of satel- lite communication systems at the expense of introduction of new types of signal-code designs, an asynchronous method of switching of packages and regeneration of signals on the board a space vehicle. Besides, application of digital proc- essing is perspective for arrangement of communication in difficult radio-electronic conditions. The new kind of sig- nals, which allow to increase noise immunity of a radio channel is offered.
