Abstract
The most complete consideration of the characteristics of the signal-noise situation in the communication channel, which are determined by the probabilistic characteristics of the interference complex consisting of chaotic pulse interference, non-Gaussian and noise interference with arbitrary fluctuations in the signal amplitudes and interference, is extremely important for most communication systems with moving objects. The developed method in this paper allows us to synthesize structural schemes of optimal and quasi-optimal devices for processing random groups of signals with arbitrarily defined distributions. At the same time resulting quasicanonical (unified) structures of algorithms and devices are convenient for both practical implementation and transition to adaptive procedures, when the number, vector of average values, covariance matrices and probabilities of the components of the distribution of useful and interfering pulses are estimated during signal processing and used to adapt the configuration of decision device during its work.
Keywords: quasi-determined algorithm for resolution, non-Gaussian signals, chaotic pulse interference.
