The Estimation of FH Signal Parameter by Multi-windows Iterative SPWVD Algorithm
Xie Yan · Journal of Air Force Engineering University · 2008
Contrast and analysis of frequency-hopped sequence based on tradition time-frequency presentation is proposed in the paper.Then the paper presents a novel method of estimating transmission parameters such as instantaneous frequency,hop duration and hopping frequency pattern by using the iterative multiple windows smoothed pseudo Wigner-Vile distribution(SPWVD).The simulation results show better recovery of the signals in a lower SNR level(-8dB).
