Modeling of stochastic processes in $L_p(T)$ using orthogonal polynomials

In this paper, models that approximate stochastic processes from the space $Su{b}_{\phi }(\mathrm{\Omega })$ with given reliability and accuracy in $L_p(T)$ are considered for some specific functions $\phi (t)$. For processes that are decomposited in series using orthonormal bases, such models are constructed in the case where elements of such decomposition cannot be found explicitly.
