Abstract
Interpolation filters are widely used in symbol timing recovery systems to interpolate new sample values at arbitrary points between the existing discrete-time samples. Polynomial interpolation is interpolated by coefficient made inputted information. This paper presents an efficient way to implement polynomial base interpolation filters using support filter changing input. By an example, it is shown that the proposed structure out performs the conventional interpolation structure with less hardware cost.
