In this paper, a particularly efficient procedure for achieving improved spectral estimations from incomplete observations of data sequences is presented. The essence of the method is that of. appropriately estimating the unobserved (or missing) data by extrapolation/interpolation and using the enlarged data base to generate the improved spectrum estimate. Clearly, the effectiveness of this method will be dependent on how well the missing data can be estimated. Empirical evidence accumulated to date indicates that this paper’s procedure is effective as well as being computationally efficient.
