Popis:	A new approach to the estimation of high resolution power spectra of harmonic processes is presented. This approach uses linear programming (LIP) to exploit the spiky character of the L 1 norm. Results for the LIP power spectral estimate are contrasted with those using various formulations of the maximum entropy algorithm.
