The new principle of construction of noise-proof satellite communication systems on the base of superbroadband signals

The opportunities of construction of new digital systems of satellite communication systems using superbroadband radiosignals are analyzed. The series of synchronized oscillations of partial carrier frequencies is used, each of which is modulated by broadband signal with similarl communication message. Radiation and reception are executed by antenna arrays with non-equidistant located aerial elements of various frequency components. Nonequality of space delays of various frequency components is compensated by adaptive search and tracking systems. The growth of interference protection is reached at the expense of increase of signal base and use of various frequency bands. The application of narrow-band circuitry re suits in the equipment simplicity and provides high efficiency. The defect by interference or failure in operation of part of the channels slightly worsen the quality of communication messages. The recommendations on the choice of system characteristics are formulated. The variants of construction of communication system with simplified structure of on-board equipment are considered.
