• Method of processing of the ionospheric signals pulse

  The new method of processing of pulse ionospheric signals is presented. It is based on positions of the theory of optimum reception. However these positions are applied to difference to the equation received after transformation of the accepted message. The theory of a method of processing is presented, the results of modeling calculations illustrating efficiency of a method ...

• Bases of the theory of digital communication systems with not orthogonal carrier frequencies

  The algorithm of the solution of the task of permission of signals in communication systems with not orthogonal carrier frequencies is provided. A basis are provisions of the theory of optimum reception in the annex to communication systems. It is shown that the system of equations of credibility allows to solve for communication systems the problem of permission of signals in the field of their nonorthogonality. It is shown that the solution ...

• A comparative evaluation of the correlation analysis and maximum likelihood method resolution in the reception of phase-shift keying signals based on Barker codes

  This article presents the results of a MATLAB-assisted study into the maximum likelihood method resolution in the reception of two radioprobing signals based on Barker’s codes. The study is based on the expressions ob-tained by the authors within optimum reception theory that make it possible to carry out a joint evaluation of the same parameters of two signals and re-solve them based on these parameters. 1.
