"... Abstract. We consider the problem of quickly estimating the best kterm Fourier representation for a given frequencysparse bandlimited signal (i.e., function) f: [0,2π] → C. In essence, this requires the identification of k of the largest magnitude frequencies of ˆf ∈ C N, and the estimation thei ..."
