Abstract :
A new method for estimating the parameters of a complex polynomial-phase signal in complex white Gaussian noise is proposed. Its computational complexity is comparable to the S.peleg´s method, but it approaches the Cramer-Rao bound (CRB) down to much lower signal-to-noise ratio (SNR) values. Simulation results are included to demonstrate the performance of the proposed method
