The probabilistic approach to synthesis of signals adaptive spatial processing robust algorithms

The case of signal processing where raditional theory results generalization for the instance when the parameters are not known exactly is analyzed. The problem of synthesis of algorithms effectively functioning in conditions of a priori uncertainty about the properties of the signal is usually formulated as a problem of a decrease in sensitivity of the procedures realizing optimum vectors of weight factors to the a priori data errors concerning the useful signal vector. By analyzing the existing works it is possible to make the conclusion that the solution can be found using two approaches: probabilistic and deterministic.
