Essay

Dissertation work is sanctified to development of methods and algorithms frequency - temporal analysis and demodulation of difficult signals in the conditions of hindrances on the basis of digital selections of minimum volume. The results of researches it is been subsequent development of theory frequency - temporal analysis of difficult signals without the use of transformation of Fourier. The decided tasks of determining the amount and face values of subbearing frequencies of OFDM of signals are formulated at a priori complete and partial vagueness on the basis of decision of the systems of linear algebraic equalizations. With the use of the systems of linear algebraic equalizations the tasks of secondary analysis of parameters are decided, that resulted in complete authentication and possibility of demodulation of OFDM of signals. The value of them consists in providing of greater discriminability on frequency as compared to the methods of Fourier - analysis at comparable requirements to computing facilities.
