Abstract :
A ladder algorithm for linear interpolation of nonstationary signals is developed. The algorithm is based on the sliding-window least-squares method and can be implemented using a lattice structure. Furthermore, by assuming that the input signal is stationary, the number of parameters required to be calculated is reduced. The lattice structure in the case of stationary input is also presented
