Abstract

We derive and analyze a suboptimal algorithm for estimating the unknown parameters of an exponential polynomial signal (EPS) model. The EPS model represents a signal as an exponent raised to a complex polynomial of time. That is, the phase and the logarithm of the amplitude are approximated as finite-order polynomials of time
