dispersion minimization

The paper substantiates the method of orthogonalization of linearly independent functions based on the calculation of the orthogonality weight. The form of orthogonal functions does not differ from the form of the original functions. Synthesis of optimal receivers is carried out based on the criterion of minimum noise variance at the receiver output for a fixed reference value of the useful signal. In the case of non-white noise, op-timal receivers have a finite gain in the entire operating frequency band.
