STUDY OF THE AREA OF DETERMINATION OF PARAMETERS OF THE BASIS FUNCTION OF TWO ARGUMENTS IN CONSTRUCTING THE Λ-ORTHOGONAL BASIS FUNCTION

The purpose of the research is to determine area setting argument τ and its discretizationintervals when constructing an algorithm for adaptive nonlinearoptimal smoothing multi-parameter data trajectory measurements, which makes it possible tojointly implement spatial temporal redundancy obtained. wascarried out by a Λ-orthogonal basis function in order obtain independent estimatesfor coefficients polynomial. It shown that advisable solve problemof determining maximum likelihood estimate coefficient vector smoothingpolynomial method successive approximations. When basisfunction, polynomial isachieved 2-3 iterations. follows from results presented paper accuracyindex Qт as two arguments ( smallest value Δτ isthe discretization interval τ) wide range values these changesslightly, but increases sharply at .
