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