Main Article Content
This paper presents a new simple phase based algorithm to estimate the frequency of a complex sinusoidal signal in complex white Gaussian noise. The proposed technique makes use of the different phase signal to estimate the unknown constant frequency of the corrupted signal. The proposed algorithm not only yields good statistical properties but also yields fast speed of convergence. Moreover, the steady state analysis for mean squared frequency error (MSE) of the estimated frequency is addressed and derived in closed form. Simulation results can assert the performance of the proposed algorithm.
