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 L1norm. Results for the LIP power spectral estimate are contrasted with those using various formulations of the maximum entropy algorithm.
