    摘要: In a VSB system, a method for channel modeling to estimate coefficients corresponding to a selected subspace is provided. The method comprises the steps of: selected a predetermined subspace; creating a set of bi-orthogonal vectors for the initially selected subspace; and obtaining a set of coefficients by solving a linear programming problem. Whereby the resultant channel is constructed by the coefficients and their associated subspace.
