Simulation on the Fast Frequency Estimation Algorithm of FH Signal

In this paper, we develop a sophisticated algorithm which has been used in our frequency estimation system of frequency-hopping(FH) signal. By combining the adaptive Pisarenko´s Harmonic Deposition(PHD) with the modified least-square-lattice(LSL) algorithm and using a proper initial tap setting, we can see that the convergence rate of this algorithm has been further increased and convergent property of the adaptive implementation of PHD has been improved. Simulating results further verify the correctness and accuracy of the algorithm.
