基于时频脊线的跳频参数盲估计
Blind Parameter Estimation of Frequency-Hopping Signals Based on the Time-Frequency Distribution Maxima
摘要
Abstract
To estimate the parameters of unknown frequency-hopping (FH) signals, a blind parameters estimation method for FH signals based on time-frequency distribution maxima is proposed. Due to the transient frequencies of FH signals, the hop period can be estimated accurately via the wavelet transform of the time-frequency distribution maxima of a FH signal. The switching time instants and the hopping frequencies can be estimated accordingly. The theoretical analysis and simulation result show that the method can accurately estimate the parameters of FH signals with a low computational complexity. The performance of this method is superior to the current existing method.关键词
