| 内容記述 | An extrapolation algorithm for discrete bandlimited signals is proposed. The bandlimited condition is satisfied by using an ideal bandlimited signal as an excited signal. A waveform synthesis digital filter is used to extrapolate fractionally observed data, using the bandlimited excited signal. Therefore, the proposed method reduces the extrapolation problem to a digital filter estimation problem. Digital filter coefficients are obtained by solving linear equations, which are formulated to minimize the mean-square error between a part of the extrapolated signal and the fractionally observed data. The modified Gram-Schmidt (MGS) procedure is applied to finding the least-square solution of the filter coefficients, due to its superior numerical stability. The recursive version of the MGS procedure is suited to real-time hardware implementation. The proposed algorithm is shown to have good performance in extrapolating the fractional data, observed in a single as well as multiple time windows. This concept is applicable not only to the signal extrapolation but also to the spectral estimation. | |||||
