Abstract:
The paper provides a review of the existing methods of signals' processing within the conditions of the Rice statistical model applicability. There are considered the principle development directions, the existing limitations and the improvement possibilities concerning the methods of solving the tasks of noise suppression and analyzed signals' filtration by the example of magnetic-resonance visualization. A conception of a new approach to joint calculation of Rician signal's both parameters has been developed based on the method of moments in two variants of its implementation. The computer simulation and the comparative analysis of the obtained numerical results have been conducted.
Keywords:
Rice distribution, magnetic-resonance visualization, samples of measurements, mean value, noise dispersion.
